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 of the structure ##STR18## wherein B is a polymeric backbone of carbon-carbon linkages derived from interpolymerized units of one or more acrylates of the formula ##STR19## wherein R' is --H, --CH.sub.3, or --C.sub.2 H.sub.5, and R" is selected from the group consisting of an alkyl radical containing 1 to 18 carbon atoms, an alkoxyalkyl radical, an alkylthioalkyl, and a cyanoalkyl radical each containing 2 to about 12 carbon atoms; A is a bivalent radical selected from the group consisting of ##STR20## --CH.sub.2 --O--CH.sub.2 --, and --CH.sub.2 --O--; 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 acrylate monomers.
- 3. A polymer of claim 2 wherein the acrylate monomer is n-butyl acrylate and A is ##STR21## .
- 4. 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.
- 5. A polymer of claim 3 wherein the polymer has a bulk viscosity at 27.degree. C. of from about 10,000 centipoises to about 400,000 centipoises.
