US Patent:

61653098, Dec 26, 2000

Filed:

Feb 4, 1998

Appl. No.:

9/018615

Inventors:

Ann Marie Burnell - Schenectady NY
John F. Lubera - Catskill NY
Terrence P. Oliver - West Lafayette OH

Assignee:

General Electric Co. - Pittsfield MA

International Classification:

B32B 3120

US Classification:

1563082

Abstract:

The present invention is directed to a method for improving the adhesion between a conductive laminate and a substrate material. In a preferred embodiment of the present invention, the conductive laminate is a copper film and the substrate material comprises polyphenylene ether resin. The method involves admixing a copolymer of a vinyl aromatic compound and an. alpha. ,. beta. -unsaturated cyclic anhydride with the polyphenylene ether resin. The copolymer of a vinyl aromatic compound and an. alpha. ,. beta. -unsaturated cyclic anhydride is preferably a polystyrene maleic anhydride copolymer or a rubber modified polystyrene maleic anhydride copolymer.

US Classification:

521 85

Abstract:

The present invention includes an improved blowing agent concentrate, comprising: (a) a vinyl aromatic polymer; (b) a preformed blend of a styrene/diene block copolymer and a hydrocarbon rubber extending oil; and (c) at least one blowing agent. The blowing agent concentrate is utilized to prepare foamable materials based on a variety of thermoplastic organic polymers. The foamable materials can in turn be molded into a variety of thermoplastic structures.

Abstract:

A process for producing structural aromatic polycarbonate thermoplastic foam is provided which involves gas expansion of a melted aromatic polycarbonate thermoplastic resin composition containing an amount of a polytetrafluoroethylene nucleating agent. The thermoplastic resin compositions provided exhibit an improved uniformity of cell structure in the resultant structural thermoplastic foam as a result of the incorporation of the polytetrafluoroethylene nucleating agent. The process and compositions are useful in the production of structural thermoplastic foam articles.
