Additives can be permanently incorporated into melt spun fibers by cold drawing the fibers under conditions that generate a network of interconnecting microvoids within the fiber. The microvoids are formed in the presence of specified liquid or vapor media which fill the microvoid network. The temperature of the medium is below the effective glass transition temperature of the fibers containing said medium. The additive is either present in said medium or is applied to drawn fibers containing said medium.

Additives can be permanently incorporated into melt spun fibers by cold drawing the fibers under conditions that generate a network of interconnecting microvoids within the fiber. The microvoids are formed concurrently with the drawing of the fiber in a non-solvent liquid or vapor media, which media fills the microvoid network. The temperature of the medium is below the effective glass transition temperature of the fibers containing said medium. The additive is either present in said medium or is applied to drawn fibers containing said medium.

The present invention relates to a partial ester derived from the reaction product of an oxirane containing acid or derivative thereof, and a reactive hydroxyl compound selected from the group consisting of diols, triols, di-diols and 1,4-dihydroxy butane and a halogen containing polymer compositon thereof. The oxirane compound can be derived from the group consisting of epoxidized vegetable oil, epoxidized fish oil, an aliphatic or arylaliphatic containing craboxyl compound having an oxirane group in the aliphatic chain.

Diorganotin compounds wherein at least one of the remaining valences on the tin atom is satisfied by a sulfur atom or a thiocyanate group are unique among diorganotin compounds in that they retain their catalytic activity over extended periods of time in the presence of the precursors or masterbatches conventionally employed to prepare rigid, cellular polyurethanes.
