Abstract
Abstract Novel polymers are disclosed which are based on an ethylenically unsaturated monomer containing at least one azide group and another ethylenically unsaturated silane monomer. These materials are useful as coupling agents for thermoformable polymers such as polyolefins and inorganic fillers. Optionally the polymers can contain other ethylenically unsaturated monomers as spacers or extenders for the more expensive azide or silane monomers.

A coupling polymer comprised of (a) 20-80% by weight of an ethylenically unsaturated monomer containing at least one azide group; (b) 20-80% by weight of an ethylenically unsaturated silane monomer wherein the silicon molecule is substituted with at least one hydrolyzable radical; (c) 0-60% by weight of an ethylenically jnsaturated monomer containing no azide or silane functional group; and (d) 0-10% by weight of an ethylenically unsaturated monomer which is capable of absorbing actinic radiation and containing no azide or silane functional group.
Claim 2
Dependent Claim
83 words
A coupling polymer comprised of (a) 20-80% by weight of an ethylenically unsaturated monomer containing at least one azide group; (b) 20-80% by weight of an ethylenically unsaturated silane monomer wherein the silicon molecule is substituted with at least one hydrolyzable radical; (c) 0-60% by weight of an ethylenically jnsaturated monomer containing no azide or silane functional group; and (d) 0-10% by weight of an ethylenically unsaturated monomer which is capable of absorbing actinic radiation and containing no azide or silane functional group.
