Rotationally Molding Crosslinkable Polyethylene Composition
US Patent:
4857257, Aug 15, 1989
Filed:
Jun 13, 1983
Appl. No.:
6/503989
Inventors:
Shu P. Chen - Baton Rouge LA
Theodore R. Engelmann - Baton Rouge LA
Harold D. Oltmann - 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:
B29C 4104
US Classification:
264310
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.

Assignee:
Allied Corporation - Morris Township, Morris County NJ
International Classification:
B32B 702, B32B 516, B32B 2734
US Classification:
428216
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.
