組成物が強く要請されている。2. Description of the Related Art In recent years, in the field of polymer materials, in combination with a variety of uses, a polymer composition having a very low elastic modulus, which has high performance, high functionality, economical efficiency and versatility, for example, There is a strong demand for a rubber composition having a low elastic modulus and a plastic composition having a very low elastic modulus.

性率化を図ることも知られているが、低分子材成分の量
に限界があるため、弾性率の大巾な低下は望めない。Conventionally, a general-purpose polymer composition having a somewhat low elastic modulus, that is, a composition containing a general-purpose polymer material component and a low-molecular material component (for example, a liquid) in a moderate amount or less is known. . It is well known that such a composition can be obtained relatively easily by mixing an appropriate amount of a low molecular weight material component having a good compatibility with a high molecular weight material component in a mixer or the like usually used in industry. However, since the amount of the low molecular weight component used is limited, the polymer composition cannot have a very low elastic modulus. A general-purpose polymer composition having a very low elastic modulus may be a composition containing a general-purpose polymer material component and a large amount of a low-molecular material component, but it is not yet known. For example, both components may be mixed with a mixer or the like so that 100 parts by weight of the polymer material component and 50 parts by weight or more of the low molecular weight component are mixed, but the polymer material component slips and a uniform polymer composition is obtained. This is because it is difficult to obtain. In this case, if the mixing is carried out very carefully and for a long time, the desired composition may be obtained, but naturally the productivity is extremely poor and it is industrially unsuitable. Further, even if it is obtained by mixing for a long time, a polymer composition containing a high amount of a low molecular weight material often lacks uniformity, and bleeding of the low molecular weight material component cannot be suppressed, and there are many problems in physical properties in terms of work. . In order to improve these drawbacks, it is known that a composition of a polymer material component and a component in which a low molecular weight material is sprinkled on a powder or the like is used to reduce the elastic modulus, but the amount of the low molecular weight material component Since there is a limit to this, a drastic decrease in elastic modulus cannot be expected.

ものとなっている。On the other hand, it is known that a polymer composition having a low elastic modulus contains, for example, a special polyurethane as a polymer material component and a large amount of a low molecular material component. However, since this polymer material component has a special structure, the low-molecular material component to be combined is limited to a special one, so that this polymer composition has a specific physical property, and thus a specific application. This polymer material component, which is narrowly limited and used, is a non-universal material and is poor in economic efficiency, and therefore has practically no versatility.

る。The medium material in the present invention is a material having a function as a medium of a low molecular weight material and a polymeric material, and is an important component for achieving the object of the present invention. Specifically, in order to enable a uniform composition of a large amount of low molecular weight material and a high molecular weight material, a high molecular weight low molecular weight material and a medium material are used. First, a product is obtained, and a polymer composition in which a desired amount of a low molecular weight material is retained is obtained by combining this with a polymer material. Even if low molecular weight material, medium material and high molecular weight material are mixed at the same time,
It cannot be a polymer composition having a low elastic modulus. Moreover, even if a large amount of low molecular weight material and a high molecular weight material are directly mixed to obtain a high molecular weight material containing a large amount of low molecular weight material, the low molecular weight material cannot be mixed uniformly and bleeding is often easy. Happened,
The desired polymer composition having a low elastic modulus cannot be obtained. Here, "holding" the low molecular weight material means that the low molecular weight material is uniformly dispersed in the medium material and the high molecular weight material, and does not bleed, or bleeding is suppressed.
Of course, the degree of bleeding can be easily controlled depending on the purpose of the polymer composition. Finally, when the low molecular weight material-holding medium composite is mixed with the polymeric material, the uniform mechanism of uniform dispersion in the material is not always clear, but many of the composites are divided into fine particles. It is considered to be retained in the polymer material.

In the present invention, both materials are selected so that the difference in solubility parameter value between the low molecular weight material and the high molecular weight material is 4 or less, and preferably 3 or less from the viewpoint of the effect. The low molecular weight material is mixed with the high molecular weight material in the form of a low molecular weight material holding medium composite, and the compatibility between the low molecular weight material and the high molecular weight material is also a problem in this case. If the difference in this parameter exceeds 4, in view of compatibility, the low molecular weight material retained in a large amount in the above composite is difficult to retain in the polymer material, which causes a decrease in the elastic modulus of the polymer composition. In addition, bleeding of low molecular weight material is likely to occur, which is not preferable.
