Abstract
A dual cure site polyacrylate polymer is provided which utilizes an aliphatic or aryl substituted urea or thiourea as a retarder to inhibit scorch during processing. While the polymer utilizes a retarder, compression set characteristics are not harmed and in fact may be enhanced by the use of the retarder.
