Abstract
Methods for preparing pre-dynamic cross-linked polymer compositions are described. Methods of preparing dynamic cross-linked polymer compositions using pre-dynamic cross-linked polymer compositions are also described.
Claims26
A method of forming an injection molded article, comprising:
- forming a pre-dynamic cross-linked polymer composition by combining in an extruder an epoxy-containing component, polyester component, and a transesterification catalyst at a temperature of up to about 320° C. for about 7 minutes or less;
- melting the pre-dynamic cross-linked polymer composition;
- and
- injecting the melted pre-dynamic cross-linked polymer composition into an injection mold to form the injection molded article.

A method of forming an article comprising a dynamic cross-linked polymer composition, comprising:
- forming a pre-dynamic cross-linked polymer composition by combining in an extruder an epoxy-containing component, a polyester component, and a transesterification catalyst at a temperature of up to about 320° C. for about 7 minutes or less;
- heating the pre-dynamic cross-linked polymer composition;
- and
- subjecting the heated pre-dynamic cross-linked polymer composition to a compression molding process, a profile extrusion process, or a blow molding process to form the article comprising the dynamic cross-linked polymer composition.
