HALOGEN SCAVENGER FOR POLYMERS AND COPOLYMERS

摘要

A solid solution is provided which is useful as a halogen-scavenging compound in polymer-containing formulations, where the polymer contains low levels of acid materials. The halogen scavenger is hydrotalcite-like composition, i.e., an aluminum magnesium hydroxy carbonate solid solution. The solid solution has a characteristic IR spectrum, which indicates bidentate coordination of carbonate, and has a crystallite size in the <003> direction of about 190 ANGSTROM to about 225 ANGSTROM .
