Novel method for reducing the processing temperature of thermoplastic polymers and novel blowing agent concentrates produced thereby

摘要

The present invention pertains to a method for reducing the processing temperature of a thermoplastic polymer comprising blending the thermoplastic polymer in powder form with an effective amount of a compound having a softening temperature of about 20 DEG to 200 DEG C. lower than the softening temperature of the thermoplastic polymer. The invention further pertains to novel chemical blowing agent concentrates.
