HIGH MELT VISCOSITY POLYESTER OR CO-POLYESTER COMPOSITIONS

摘要

Processes of decreasing the melt flow rate of a polyester selected from the group consisting of polyesters derived from one or more dicarboxylic acids and one or more diols having more than two carbon atoms, copolyester thermoplastic elastomers, and mixtures of these, by melt mixing with the polyester an alkali metal salt having a molecular weight less than 300 to provide a melt mixed composition. Processes of making a melt extruded article from such melt mixed compositions and the articles made therefrom.
