Abstract
A novel terminally functional (i.e., telechelic) polymers having a polyisobutylene are described. The end groups are styryl and can be reacted with conventional monomers to form copolymers having unique physical properties. Copolymerizations with N-vinyl-2-pyrrolidone produce amphiphilic polymers which are useful in the areas of medicine and agricultural chemicals.
Claims7
A telechelic polyisobutylene, comprising:
- ##STR11## wherein PIB is polyisobutylene having a molecular weight from about 500 to about 50,000, n is two or three and R is --H or --CH.sub.3.
A copolymer comprising:
- the reaction product of:
- ##STR12## wherein PIB is polyisobutylene having a molecular weight from about 500 to about 50,000, n is two or three and R is --H or --CH.sub.3,
- and a monomer selected from the group consisting of N-vinyl-2-pyrrolidone, hydroxyethyl methacrylate, acrylamide and vinyl acetate;
- wherein said copolymer is amphiphilic.
