Definitions
- cycloolefin polymers have been the subject of many publications in recent times. It is known that these olefins can be polymerized using various catalysts. Depending on the catalyst, the polymerization proceeds via ring opening (US-A-3557072, US-A-4178424) or with opening of the double bond (EP-A-156464, EP-A-283164, EP-A-291208, EP-A -291970, DE-A-3922546).
- Cycloolefin homo- and copolymers are a class of polymers with an outstanding level of properties. Among other things, they excel from high heat resistance, hydrolytic stability, low water absorption, weather resistance and transparency. However, the processability at high temperatures and shear forces is limited by oxidative and thermal processes. Additives such as antioxidants and thermal stabilizers are used to increase the thermal processing range. High levels of additives can lead to a strong negative impact on mechanical properties such as the modulus of elasticity and the tensile strength. Additives can thus act as plasticizers, whereby the shear modulus is also reduced over a wide temperature range.
- the flowability of the polymer can be improved by flow improvers such as PE waxes.
- flow improvers such as PE waxes.
- Polyaryl ether ketones are also well known, as evidenced by the large number of publications on synthesis and properties: US-A-3953400; US-A-3956240; US-A-4247682; US-A-4320224; US-A-4339568; Polymer 22: 1096-1103 (1981); Polymer 24 (1983), 953-958.
- Polyaryl ether ketones are also a valuable class of polymers, which are characterized, among other things, by good impact strength and high thermal resistance. Some polyaryl ether ketones are highly crystalline and show melting temperatures of well over 300 ° C, others are amorphous.
- Amorphous and partially crystalline polyaryl ether ketones with different molecular weights can be obtained by electrophilic aromatic substitution (US-A-3065205; US-A-3956240) or nucleophilic aromatic substitution (J. Polymer Sei., 1967, A-1, 5, 2415-2427; US -A-4107837; US-A-4175175, DE-B-1545106, CA-A-847963, DE-A-2803873).
