Title:
COMPOSITIONS OF POLYHYDRIC ALCOHOLS AND POLYAMIDES
Document Type and Number:
WIPO Patent Application WO/2013/033287
Kind Code:
A3
Abstract:
The present invention relates to a thermoplastic composition that provides improved thermal aging stability along with durability. The thermoplastic composition comprises a polyamide resin, and a polyhydric alcohol, wherein a majority of the polyhydric alcohol particles have a particle size that is less than about 70 microns. It has been found that a combination of a polyamide resin and a polyhydric alcohol with this particle size produces a superior product demonstrating greater thermal stability and durability than the polyamide resin alone.
