Abstract
The invention relates to a product and process for producing molded unsaturated polyester products. An unsaturated polyester is formulated with two initiators in combination with two reagents which scavenge free radicals; one of the scavengers traps free radicals which occur at low temperatures of 20 to 50° C.; whereas the second scavenger traps free radical which are produced and occur in the compositions at temperatures above those low temperatures. The compositions of the invention eliminate premature gelling and insure shelf life.
