摘要:
Preparation of new copolymers of olefins or olefins and nonconjugated dienes with norbonene derivatives, by co-ordination catalysis. The norbornene derivatives are selected from those with the formula
WHERE Q IS AN INTEGER WHICH MAY EQUAL FROM 0 TO 12, P EQUALS 0 OR 1, R1 represents a pyridyl radical, where p equals 0, and an alkyl radical, where p equals 1, and R2 to R8 represent hydrogen or hydrocarbon radicals with from one to 12 carbon atoms. These derivatives are, notably, the adducts of cyclopentadiene and vinylpyridine or alkyl acrylates or methacrylates.
摘要:
Cycloalkenyl tricycloalkenes are novel polycyclic compounds which may include substituents such as methyl, ethyl or others. They can be prepared by reacting a substituted or unsubstituted cyclic 1,3-diene with a 2,2'' -dicycloalkenyl compound. The cycloalkenyl tricycloalkenes can be used to produce elastomers by copolymerization with non-conjugated polyenes and/or olefins.
