Claims
- 1. In a fiber-and film-forming lactam polymer composition which contains between 0.05 and 5%, based on the weight of said polymer, of an alkali metal salt of said lactam, the improvement which resides in the presence in said composition of between 0.5 and 100%, based on the weight of said alkali metal salt, of a hexaorgano distannane exhibiting the formula R.sub.3.sup.2 SnSnR.sub.3.sup.3, wherein R.sup.2 and R.sup.3 are each selected from the group consisting of alkyl radicals containing between 1 and 20 carbon atoms.
- 2. The lactam polymer composition of claim 1 wherein R.sup.2 and R.sup.3 are butyl radicals.
- 3. The lactam polymer composition of claim 1 wherein the lactam is .epsilon.-caprolactam.
- 4. The lactam polymer composition of claim 1 wherein the alkali metal is sodium.
