EXPANDABLE THERMOPLASTIC POLYMER PARTICLES AND METHOD FOR MAKING THE SAME

摘要

An improved process for manufacture of expandable polymer particles is provided. The continuous process disclosed produces expandable polymer pelle ts in a single step while eliminating many of the dangers inherent in processes of prior art employed for the same. The polymers produced herein are of uniform size, and may be molded into various articles of manufacture using existing equipment and techniques known to those skilled in the art.
