Novel compositions of silicone/polyether block copolymers are provided which are useful as surfactants in several classes of polyurethane foam production. While conventional copolymers have a polysiloxane backbone with pendant polyethers, the surfactants of the present invention are the reverse with siloxane pendants on a polyether chain. These novel non-hydrolyzable polysiloxane polyoxyalkylene copolymers which are characterized by an 'inverted' structure, i.e., polyoxyalkylene backbones with lateral and/or terminally pendant polysiloxanes, represent species that are of a narrow molecular weight and compositional distribution and are free of unreacted polyether or non-modified silicone oil diluent. These surfactants are useful in various urethan foam systems and can also display aqueous wetting properties.

Polyester resin is modified with siloxane block polymers in such a manner so as to form silicone-modified polyester copolymer domains of controlled size and distribution dispersed in the polyester matrix. These domains undergo microphase segregation and migration during the melt spinning and cold-drawing to the surface of the polyester fiber being formed so as to provide a silicone-sheathed polyester fiber.

Silicone-modified polyester resin and silicone-sheathed polyester fibers

Compositions comprising higher alkyl modified epoxy silicone terpolymers having the general formula:

Textiles treated with higher alkyl modified epoxy terpolymeric silicones

A process for imparting lubricity to fibers which comprises applying a graft copolymer of an N-(oxymethyl)-acrylamide and a poly(oxyalkylene) to the surface of the fiber and crosslinking the graft copolymer on the surface of the fiber.

Process for imparting lubricity to fiberfill fiber

Crosslinkable graft copolymers of poly(oxyalkylene) are provided which comprise from about 1 percent by weight of a substituted N-methylol derivative of acrylamide grafted onto a poly(oxyalkylene)-polymer.
