6/444228

Inventors:

Ping Y. Liu - Naperville IL

Assignee:

General Electric Company - Pittsfield MA

International Classification:

C08L 6702

US Classification:

525177

Abstract:

A modified thermoplastic molding composition having improved compatibility and mold releasability the composition comprising a thermoplastic polyester resin selected from the group consisting of polyethylene terephthalate, poly(1,4-butylene terephthalate), a co-polyester or any combination thereof and from about 0. 1 to about 20% by weight based on the total composition of linear low density polyethylene. Optionally, the composition may have added thereto an effective amount of an aromatic polycarbonate for impact strength. The compositions may also contain an effective amount of at least one additive selected from the group consisting of fillers, reinforcing agents, nucleating agents, flow promoters, coloring agents, flame retardants, coupling agents and stabilizers.
