1. A random copolymer comprising:
- (a) recurring units each having the formula of;
##STR8## wherein R1 to R10 each represent the same or different atoms or groups and stand for a hydrogen atom or an alkyl group with or without R5 being bonded to R6 or R10 via an alkylene group having 1 to 3 carbon atoms,(b) said random copolymer being obtained by copolymerizing ethylene with a feed monomer material comprising a 5-aryl-bicyclo [2.2.1] hept-2-ene compound represented by the formula of;
##STR9## wherein R1 to R10 are the same as above, (c) said random copolymer containing 50 to 90 mol % of ethylene,(d) said random copolymer having an intrinsic viscosity [η
] of 0.3 to 10 dl/g measured in decahydronophthalene at 30°
C., and(e) said random copolymer having a glass transition temperature (Tg) of 80°
to 220°
C. measured by a thermomechanical analyzer.

Abstract
A random copolymer comprises recurring units each having the formula of; ##STR1## wherein R1 to R10 stand for a hydrogen atom or an alkyl group with or without R5 being bonded to R6 or R10 via an alkylene group having 1 to 3 carbon atoms. The random copolymer contains 50 to 90 mol % of ethylene. The random copolymer has an intrinsic viscosity [η] of 0.3 to 10 dl/g measured in Decalin®, i.e., decahydronphthalene at 30° C.
