Claims13
An ester-containing halogenated polyalkylene characterized by internal olefinic unsaturation, by being essentially free of crosslinking, by having a branch index of from about 2 to about 20 and by having a halogen content of from about 0.001 percent to less than about one percent by weight based on polyalkylene and, conversely, having an ester content of greater than about 99 percent.
An ester-containing chlorinated linear polyethylene further characterized by:
- (a) internal olefinic unsaturation
- (b) being essentially free of crosslinking
- (c) having a branch index of under about 3
- (d) having a halogen content of from about 0.001 to less than about one percent by weight based on polyethylene.
