Chemical products from cured unsaturated polyesters

Abstract

Abstract Recovery of value from cured unsaturated polyesters, other than the approach of grinding the resin and blending it with virgin resin for applications of minor importance, has been difficult. The long established position of the resins in the marketplace, their complex composition, and economic considerations have been major obstacles. This article reports results obtained on recovery of soluble, well‐characterized products from cured resins by neutral hydrolysis and on some experimental applications of the products. © 1993 by John Wiley & Sons, Inc.
