Patent ID: 10787533

Abstract:
This invention relates to a novel one-pot process for polyolefin modification to form long-chain branched polymers containing polar functional groups, and the long-chain branched polymer resulting from the process. The process comprises reacting the following components (a) through (d) in a one pot process to form a long-chain branched polyolefin. Component (a) is a polyolefin; component (b) includes one or more silane compounds having the formula R″SiRnR′(3-n), component (c) is an ethylenically unsaturated polycarboxylic acid; and component (d) is a free radical initiator. In the formula R″SiRnR′(3-n) for component (b), R″ is an ethylenically or acetylenically unsaturated radical; R is a hydrolyzable group selected from the group consisting of an alkoxy, acyloxy, alkylamino, and arylamino; R′ is a hydrocarbyl group having 1 to 6 carbon atoms; and n is 1, 2, or 3.
