Claims
- 1. A liquid vinylidene-terminated polymer having a molecular weight of from about 1000 to about 20,000 as measured using a Mechrolab Vapor Pressure Osmometer and of the structure ##STR18## wherein B is a polymeric backbone of carbon-carbon linkages derived from polymerized units of dienes containing 4 to about 10 carbon atoms interpolymerized with vinyl nitriles and R is hydrogen or an alkyl radical containing 1 to 4 carbon atoms.
- 2. A polymer of claim 1 wherein B consists of polymerized units of butadiene and acrylonitrile monomers.
- 3. A polymer of claim 2 wherein the polymer has a bulk viscosity at 27.degree. C. of from about 5000 centipoises to about 2,000,000 centipoises.
- 4. A polymer of claim 3 where in the structure R is hydrogen and the polymer has a bulk viscosity at 27.degree. C. of from about 10,000 centipoises to about 400,000 centipoises.
