Clay-containing polymer composition and its preparation and applications.

Abstract

A clay-contg. polymer compn. is prepd. by mixing an inorg. anionic clay, such as hydrotalcite or meixnerite, and a cyclic monomer selected from cyclic esters, carbonates, anhydrides, lactams, monoepoxides, bisepoxides, and siloxane, and polymg. at 50-250° in the absence of initiator or catalyst. The above polymer compn. can be dispersed in a polymer matrix selected from polyolefins, polyesters, vinyl polymers, acrylic resins, epoxy resins, polycarbonates, polyamides, polyaramids, polyimides, polyamino acids, polysaccharides, polyurethanes, and polysulfones, and the compn. can be used in coating, ink, cleaning, cement, plaster, or paper. Thus, hydrotalcite (DHT 4A) was mixed with ε-caprolactone and then polymd. at 160°. [on SciFinder(R)]
