Abstract
A method for the nucleation of polyolefins containing residual polymerization catalyst by blending the polyolefins with at least one aliphatic dicarboxylic acid containing from about 4 to about 21 carbon atoms and at least one aliphatic monocarboxylic acid containing from about 8 to about 24 carbon atoms in a weight ratio between about 4:1 and about 1:4. Also a composition comprising at least one aliphatic dicarboxylic acid containing from about 4 to about 21 carbon atoms and at least one aliphatic monocarboxylic acid containing from about 8 to about 24 carbon atoms. The polyolefin product of the nucleation can be molded into shaped articles.
