Abstract
Polylactide polymers are reacted with an epoxy-functional acrylate polymer to introduce long-chain branching into the polymer. The acrylate polymer provides a flexible means for introducing a controllable amount of branching into the polylactide polymer, with little risk of forming gelled or highly crosslinked structures. The branched polylactide polymers have excellent melt rheological properties that make them more easily processable in various melt-processing applications.
