Coating formulations which behave as elastic solids having reversible stress-induced fluidity are prepared by creating a fluid having distributed therein effective amounts of ionic charge sites and countercharge sites. For instance, elastic solids having reversible stress-induced fluidity are prepared by combining liquid formulations with a dispersion of a small, but effective, amount of at least one crystalline mixed metal hydroxide conforming substantially to the formula

Coating composition comprising solids having reversible stress-induced

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

A polymeric laminate and packaging material produced therefrom have (a) at least one conductive layer and (b) at least one static dissipative layer comprising a polymer composition having dispersed therein a non-volatile ionizable metal salt, said static dissipative layer being in electrical contact with the conductive layer. Such a laminate is found to provide shielding and static dissipation suitable for packaging of electrostatically sensitive items such as electronic components.

Conductive polymer laminates

Crystalline layered mixed metal hydroxides (LMMHs) which are substantially free of unbound water and which conform substantially to the general formula

In a process for producing polyurethane foam by allowing a reaction mixture comprising at least one polyisocyanate component and at least one polyfunctional active hydrogen component to react, a compound selected from the group consisting of oxynitrate salts of metals of Group IV B of the Mendeleef periodic table, is employed as a cell opening additive. Such oxynitrate salts are also effective to modify tin tolerance of urethane formulations. The oxynitrate compounds are effective in both free rise and molded foam processes. Cell opening is accomplished, for instance, by reacting toluene diisocyanate with a polypropoxy/polyethoxy polyol in the presence of an oxynitrate salt of a Group IV B metal, such as zirconium oxynitrate, to form a foam having more open cells than a similar foam without oxynitrate.
