This invention is a polymer containing a plurality of ketone groups in the polymer backbone and containing an amount of a non-volatile, ionizable metal salt sufficient to render it static dissipative. The polymer is substantially devoid of a fatty acid salt, a C.sub.6 -C.sub.30 carboxylic acid ester and a phosphate ester compound. The static dissipative polymer can be used neat or blended with other polymers for use in applications requiring static dissipative behavior.

Static dissipative interpolymers

This invention is an antistatic thermoplastic, phase-segregated polyurethane containing, as an antistatic additive an effective amount of a monovalent metal tetraphenylboron salt, in the substantial absence of a fatty acid salt, a C.sub.6 -C.sub.30 carboxylic acid ester or phosphate ester compound. Suprisingly, it has been found that, with this particular type of polyurethane, tetraphenylboron salts are very effective antistatic additives even in the absence of enhancer compounds as were previously employed. Accordingly, the antistatic polyurethane is useful for applications such as electronics components and packaging, and other applications where static dissipative ability is needed or desirable.

Antistatic phase-segregated polyurethanes

This invention is an antistatic polyurethane shoe sole which is prepared by reacting in a closed mold a reaction mixture comprising

An antistatic additive for polymers, particularly polyurethanes, is disclosed. The additive comprises an ionizable metal salt of a fluoroalkyl sulfonic acid and an enhancer. The enhancer is generally a salt or ester of a carboxylic acid or a phosphate ester.

Organic composition containing a fluoroalkyl sulfonic acid salt

Butene-1 and ethylene mixtures are made by reacting ethylene with a trialkyl aluminum in a boiling bed reactor. The process is more efficient in that it is selective for making butene-1 and more butene-1 is produced per unit weight of the trialkyl aluminum.
