The invention disclosed is for a method of preparing a new low shrink, one component polyester resin system which may be used in either bulk or sheet molding compounds. It may also be used in liquid form, at ambient or elevated temperatures, in casting or molding techniques of the polyester resin art. The one component polyester resin system consists of a mixture of unsaturated polyester resin, monomeric copolymerizable component and cellulose organic ester. Optional materials such as fillers, glass fibers, pigments, release agents, catalysts and the like may be added, according to the specific fabrication technique to be employed, to provide a system which displays little or no shrinkage during curing.
