Disclosed is a selected type of copolymer composition comprising copolymers having units derived from ethylene and dicyclopentadiene (DCPD) co-monomers. Such copolymer compositions: a) have a DCPD-derived comonomer unit content of from about 25 mole % to about 45 mole %; b) have a Weight Average Molecular Weight, M, of greater than about 170,000; c) comprise amorphous material and have glass transition temperatures, T, of from about 8&#xb0; C. to about 129&#xb0; C., which also fit the equation T(in &#xb0; C.)&#x2267;[(mole % DCPD&#xd7;3.142)&#x2212;4.67]; and d) comprise no significant amount of crystalline polyethylene homopolymer or crystallizable polyethylene segments within the ethylene-dicyclopentadiene copolymers. Such copolymers can be readily derivatized by hydrogenation and/or epoxidation to provide polymeric materials suitable for use as engineering thermoplastics. Also disclosed are processes for preparing and optionally further derivatizing ethylene/dicyclopentadiene copolymers having the characteristics hereinbefore described.
