(57) Abstract: A telechelic, branched, star-shaped thermoplastic polymer is produced. A mixture of a free radical initiator, at least one first free radical reactive monomer, at least one free radical reactive branching agent compound and at least one stable free radical agent is heated to polymerize the monomer. Producing a linear or unbranched polymer product having a free radical initiator segment at one end of the chain and a stable free radical agent covalently bonded at the other end, and a reactive compound, such as a free radical reactive monomer A method for producing a branched thermoplastic resin, comprising irradiating a non-branched polymer product in the presence of a branching agent compound and a mixture thereof to form a branched polymer product. |
