Abstract
An antistatic additive for polymers, particularly polyurethanes is disclosed comprising an ionizable metal salt and an enhancer comprising a non-ionizable salt or ester of an organic acid.
Claims29
An organic polymer composition comprising an organic polymer having dispersed therein
- (a) a non-volatile ionizable metal salt and
- (b) an enhancer compound comprising a salt or ester of a carboxylic acid, which salt or ester contains about 6 to about 30 carbon atoms and is compatible with said organic polymer, and in which said metal salt is soluble, wherein from about 1 to about 25 moles of said enhancer are present per mole of ionizable metal salt.
An active hydrogen containing composition comprising a polyahl or polyahls having dispersed therein
- (a) a non-volatile ionizable metal salt and
- (b) an enhancer comprising a salt or ester of a carboxylic acid containing about 6 to about 30 carbon atoms, wherein said ionizable salt and enhancer are present in an amount sufficient to increase the conductivity of an organic polyisocyanate polymer prepared from said active hydrogen containing composition, and wherein from about 1 to about 25 moles of said enhancer are present per mole of ionizable metal salt.
An additive for increasing the conductivity of an organic polymer, comprising
- (a) a non-volatile ionizable metal salt and
- (b) an enhancer which comprises a salt or ester of a carboxylic acid containing about 6 to about 30 carbon atoms, in which salt or ester said metal salt is soluble, which enhancer increases the conductivity of a polymer containing said ionizable salt, but which does not substantially increase the conductivity of said organic polymer in the substantial absence of said ionizable salt, and wherein from about 1 to about 25 moles of said enhancer are present per mole of ionizable metal salt.
