Abstract
An antistatic agent for polymers, particularly polyurethanes is disclosed comprising an ionizable metal salt and an enhancer comprising a phosphate ester.
Claims15
An organic polymer composition comprising an organic polymer having dispersed therein
- (a) an alkali metal tetraorganoboride and
- (b) an enhancer compound comprising a phosphate ester which is compatible with said organic polymer and in which said alkali metal tetraorganoboride is soluble.
An active hydrogen containing composition comprising a polyahl or mixture of polyahls having dispersed therein
- (a) a non-volatile alkali metal tetraorganoboride and
- (b) an enhancer comprising a phosphate ester wherein said alkali metal tetraorganoboride and enhancer are present in an amount sufficient to increase the conductivity of an organic polyisocyanate polymer prepared from said active hydrogen containing composition.
An additive for increasing the conductivity of an organic polymer, comprising
- (a) an alkali metal tetraorganoboride and
- (b) an enhancer comprising a phosphate ester in which said alkali metal tetraorganoboride is soluble which enhancer increases the conductivity of a polymer containing said alkali metal tetraorganoboride, but which does not substantially increase the conductivity of said organic polymer in the substantial absence of said alkali metal tetraorganoboride.
