Polyethermethylsiloxanes (PEMS) are copolymers consisting of a siloxane backbone with one or more methyl groups on the silicon atom substituted with a polyoxyalkylene (i. e. polyether) group. Commercial PEMS materials are used for a wide variety of applications, including the manufacture of polyurethane foams, textiles, personal care products, paints, and surface coatings. This chapter summarizes the structure, manufacturing processes, and applications of this important class of organosilicon compounds. In addition, the physical and chemical properties of PEMS are addressed in relation to the transport, fate, and effects of these materials in the environment.
