Abstract:
A random copolymer based on non-conjugated cyclic polyene comprising structural units originated from one or more &agr;-olefins (A1) and originated from one or more non-conjugated cyclic polyenes (A2), the said random copolymer having characteristic features comprising:a content of the structural unit(s) originated from the said one or more &agr;-olefins (A1) in the range of 93 to 70 mole %, a content of the structural units originated from the said one or more non-conjugated cyclic polyenes (A2) in the range of 7 to 30 mole %, an intrinsic viscosity [&eegr;], determined in decahydronaphthalene at 135Â° C., in the range of 0.01 to 20 dl/g, a glass transition temperature (Tg) of âˆ’30Â° C. to +40Â° C., and an iodine value in the range of 35 to 150.
