Abstract
A thermoplastic compound is disclosed comprising a macrocyclic poly(alkylene dicarboxylate) oligomer and an effective amount of a property-modifying additive selected from the group consisting of a thermal conductivity additive, an electrical conductivity additive, a sound dampening additive, an ionizing-radiation-opacity additive, an atomic-particle-moderating additive, and combinations thereof. Preferred macrocyclic poly(alkylene dicarboxylate) oligomers are cyclic polybutylene terephthalate and cyclic polyethylene terephthalate. The property-modifying additives enhance the existing manufacturing and use performance of the macrocyclic poly(alkylene dicarboxylate) oligomers.

A thermoplastic compound, comprising:
- a macrocyclic poly(alkylene dicarboxylate) oligomer and an effective amount of a property-modifying additive selected from the group consisting of a thermal conductivity additive, an electrical conductivity additive, a sound dampening additive, an ionizing-radiation-opacity additive, an atomic-particle-moderating additive, and combinations thereof.
A method of modifying properties of a macrocyclic poly(alkylene dicarboxylate) oligomer, comprising the step of mixing into the macrocyclic poly(alkylene dicarboxylate) oligomer a property-modifying additive selected from the group consisting of a thermal conductivity additive, an electrical conductivity additive, a sound dampening additive, an ionizing-radiation- opacity additive, an atomic-particle-moderating additive, and combinations thereof.
