Abstract
A fast crystallizing polymer composition comprising (1) a 1,5-pentanediol-based polyester material comprising at least one aliphatic acid and/or aromatic diacid, and (2) a nucleating agent, such as a poly(ethylene-co-methacrylic acid) ionomer and/or a poly(ethylene-co-acrylic acid) ionomer, and a method of making such wherein the polymer composition crystallizes within a period of about 30 seconds or less.
Claims24
A method of forming a polymer composition, comprising:
- (1) providing a 1,5-pentanediol-based polyester material comprising 1,5-pentanediol (PDO) and a mixture of at least one aliphatic acid and at least one aromatic diacid;
- (2) heating the PDO-based polyester material to a temperature sufficient to form melted 1,5-pentanediol-based polyester material;
- (3) providing at least one nucleating agent (NA) selected from the group consisting of a poly(ethylene-co-methacrylic acid) ionomer and a poly(ethylene-co-acrylic acid) ionomer;
- and
- (4) combining the at least one NA with the melted PDO-based polyester material to form a mixture, and further comprising combining a coupling agent with the mixture, and wherein the mixture forms a crystallized PDO-based polyester material.
