Solid state modification of propylene polymers |
摘要 |
A process for improving the melt characteristics of propylene-ethylene random block and impact copolymers is provided. The process involves contacting a powder of the copolymer with a low level of free radical initiator followed by heating at a temperature below the melting point of the copolymer and above the free radical initiation temperature.
