Abstract

PURPOSE:To improve the temp. dependence of a polynorbornene resin in a low-temp. range while retaining its inherent characteristics by compounding a low-rebound compsn. mainly comprising the polynorbornene resin with natural rubber. CONSTITUTION:A low-rebound compsn. obtd. by compounding a polynorbornene resin with a petroleum oil, a petroleum resin, a carbon black, a white filler, a vulcanizing agent, etc., is compounded with 100-300 pts.wt., pref. 150-250 pts.wt., still pref. about 200 pts.wt., natural rubber (based on 100 pts.wt. polynorbornene resin in the low rebound compsn.) to give a polynorbornene compsn. of which the temp. dependence of rebound properties has been improved in a low temp. range of -30 to 100 deg.C, esp. -30 to 20 deg.C.

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to polynorbornene resin compositions. More specifically, the present invention relates to a polynorbornene resin composition that forms a low-resilience body.

In the case of polynorbornene resin, ultra-low impact resilience can be obtained by blending a large amount of petroleum-based oil or petroleum-based resin with it, and formulations containing vulcanizing agents are also commercially available (
For example, 1 Nippon Zeon product NX552).

Such a low-resilience compound mainly composed of polynorbornene resin has the disadvantage that its characteristics are limited to the room temperature range, and it freezes from around 0 to 5°C, while its elasticity increases at temperatures above 40°C.

Various methods have been studied to solve these problems, but for example, when blending with other polymers, there are limitations in compatibility and vulcanization systems, and the types and amounts of oils and plasticizers to be blended are limited. In the study, although the temperature dependence was improved, the impact resilience was high, and ultra-high filling formulations did not provide any fundamental improvement.

決め手を欠いているのが現状である。The current situation is that we lack a decisive factor.

If the proportion of natural rubber added is less than this, although the elasticity is low, the temperature dependence, especially in the low temperature range, will not be improved; on the other hand, if the proportion is greater than this, the temperature dependence will be improved. However, the original properties of polynorbornene resin are lost.
