Foamable polyester compositions having a low level of unreacted branching agent |
摘要 |
This invention relates to a process for preparing foamable branched polyester compositions having increased melt viscosity and melt strength, and a reduced level of unreacted monomeric branching agent. The process involves melt blending (A) a composition containing a polyolefin and branching agent, (B) a nucleating agent either in powder form or (B') in the form of a composition containing a polyolefin and nucleating agent, and a polyester.
