Nylon Compositions With Superior Film Properties And Impact Strength

US Patent:
4970274, Nov 13, 1990
Filed:
May 1, 1989
Appl. No.:
7/346264
Inventors:
Varkki P. Chacko - Summit NJ
George M. Johns - Morristown NJ
Mocherla K. Rao - Woodbridge NJ
Michael F. Tubridy - Morristown NJ
Donald F. Stewart - Whippany NJ
Assignee:
Allied-Signal Inc. - Morris Township, Morris County NJ
International Classification:
C08L 7700
US Classification:
525432
Abstract:
Nylon compositions useful for molding and film applications with film properties and impact strength are made of a polyamide resin and a block copolymer of poly(amide-ether) of the formula ##STR1## where R is an alkyl or substituted alkyl group with from one to 12 carbons, n is an integer from 2 to 20, m is an integer from 2 to 6, and x and y are numbers from about 50 to about 30,000. In one embodiment, a non-polymeric amide is added to the composition. Articles made from the claimed compositions have improved impact strength; films made from the compositions have improved drapeability over the unmodified resin, both at room temperature and after heat-aging. Reinforced compositions are obtained by including mineral and other reinforcing fillers, including glass fibers, in the extrusion process. The reinforced compositions exhibit improved impact characteristics.
