Claims
- 1. A copolymer comprising cyclopentene, dicyclopentadiene and from about 0.01 to about 0.3 mole of at least one nonconjugated acyclic olefin polymerized therewith per mole of total cyclopentene and dicyclopentadiene monomer, said nonconjugated acyclic olefin having at least one hydrogen on each double-bonded carbon atom and 2 to 12 carbon atoms, and said dicyclopentadiene being present in an amount from about 55% to about 98% by weight of the total weight of copolymer.
- 2. A copolymer of claim 1 wherein dicyclopentadiene is present in an amount from about 60% to about 80% by weight of the total weight of copolymer.
- 3. A copolymer of claim 2 wherein said nonconjugated acyclic olefin is a 1-olefin or 2-olefin containing from 2 to 8 carbon atoms.
- 4. A copolymer of claim 3 wherein said 1-olefin is 1-butene.
