ABSTRACT:
Method of promoting the cure of unsaturated polyester resins with a peroxide initiator at room or below room temperatures (low temperatures) by including as a promoter N,N-dimethyl-p-toluidine (DMPT) or a blend of DMPT and N,N-dimethyl-m-toluidine (DMMT) and to the polyester composition containing such promoter. The use of the DMPT or blend of DMPT and DMMT as a promoter provides a fast cure at low temperatures without loss of physical properties of the cured resins.
