Abstract

A reinforced molding material having high tensile strength comprising: PA1 (a) from 0 to 98 parts by weight of one or more thermoplastics, PA1 (b) from 2 to 100 parts by weight of a substantially amorphous polyolefin which has been subjected to free radical grafting with a silane which has at least one olefinic double bond and one to three alkoxy groups bonded directly to the silicon, this grafted polyolefin having a melt viscosity at 190.degree. C. In the range from 100 to 50,000 maps and the parts by weight of (a) and (b) sunning to 100, and PA1 (c) from 0.5 to 400 parts by weight of a reinforcing material. The molding material can be used, inter alia, for shaped articles, as hotmelt adhesives or for heavy-duty carpet backing materials.
