Filed:

Dec 16, 1988

Appl. No.:

7/285674

Inventors:

Shu P. Chen - Baton Rouge LA
Theodore R. Engelmann - Baton Rouge LA
Harold D. Oltmann - Baton Rouge LA

Assignee:

Allied-Signal Inc. - Morris Township Morris County NJ

International Classification:

C08F25502
C08F 514
C08F 532

US Classification:

525264

Abstract:

The present invention relates to a composition comprising crosslinkable polyethylene homopolymer, copolymer or mixture thereof. The composition includes a peroxide crosslinking agent, a crosslinking co-agent, and a metal compound having a cation selected from Group IIA and IIB of the Periodic Table of Elements. The composition is particularly useful for polymers which are formed using Ziegler-type catalysts and have complete terminal saturation. The present invention also includes a composition which has been found particularly suitable for use in critical molding processes such as rotational molding. This composition comprises a polyethylene homopolymer, copolymer, or mixture thereof. The present invention includes a method of rotational molding.

International Classification:

B32B 516
B32B 2708

US Classification:

428220

Abstract:

Thin polymer films containing small sized platelet type filler. The polymer has a melt index of from 0. 01 to 10 grams per 10 minutes at 190. degree. C. to 250. degree. C. as measured on ASTM Test No. D-1238 at a load of 1000 to 2160 grams. The preferred polymer is polycaprolactam or high density polyethylene. There is from 10 to 50 percent of a platelet filler having an average equivalent diameter of from 1 to 8 micrometers, a maximum equivalent diameter of about 25 micrometers, and an average thickness of less than 0. 5 micrometers. The preferred filler is talc. The film is from 10 to 100 micrometers thick and can be a single ply or a laminate.
