METHOD AND COMPOSITION RELATING TO EMULSION-POLYMERIZED POLYDIMETHYLSILOXANES IN DURABLE PRESS RESINS Abstract of the Disclosure Silicone-containing durable press resin compositions are prepared by polymerizing a polydimethylsiloxane which has been emulsified in an aqueous solution of dimethylolethylene urea or dimethyloldihydroxyethylene urea. The resulting homogeneous aqueous compositions have improved resistance to separation after freeze-thaw cycling. Advantageously, more highly concentrated aqueous compositions comprising a silicone-containing durable press resin are available by the method of this invention. The silicone-containing durable press resin compositions are useful for providing wrinkle- recovery and permanent press to cellulose-containing fabrics.
