    摘要: Low-density polyester foams are prepared from an admixture which comprises in combination a liquid unsaturated curable polyester resin, a peroxide curing agent, an accelerator, a hydrazide blowing agent and a redox compound which adjusts the rate of polymerization of the resin, so as to expand the resin in a selective emanner to obtain a low-density, uniform, polyester foam.
