Finely-divided particulate additives for polymers with a surface coating comprised of a compound selected from the group consisting of esters of difunctional C.sub.6 -C.sub.40 aliphatic and aromatic carboxylic acids and triesters of phosphoric acid.

Surface-coated particulate additives for polymers

Novel conjugated amino substituted phenylene polymers are disclosed having on-linear optical properties, and which can be converted to electrically conductive polymers. Such polymers are produced by reacting a novel bis-cycloalkylene sulfonium salt of 2,5,N,N-tetramethylaniline hydrochloride, such as 2,5-(N,N-dimethyl)aniline hydrochloride dimethylene bis-(tetramethylene sulfonium chloride) with alkali metal hydroxide to form a cycloalkylene sulfonium salt precursor polymer, and then heating the precursor polymer under conditions to produce the amino substituted phenylene vinylene polymer, such as poly(2-(N,N-dimethylamino) phenylene vinylene). The polymers can also be made directly by treatment of the bis chlormethyl dimethyl aniline hydrochloride derivative with alkali metal alkoxide.

Polymers with electrical and non-linear optical properties

A process for synthesizing novel conjugated amino substituted phenylene pmers is disclosed. The process results in polymers having non-linear optical properties, and the polymers can be converted to electrically conductive polymers. The process involves reacting a novel bis-cycloalkylene sulfonium salt of 2,5,N,N-tetramethylaniline hydrochloride, such as 2,5-(N,N-dimethyl)aniline hydrochloride dimethylene bis-(tetramethylene sulfonium chloride) with alkali metal hydroxide to form a cycloalkylene sulfonium salt precursor polymer, and then heating the precursor polymer under conditions to produce the amino substituted phenylene vinylene polymer, such as poly(2-(N,N-dimethylamino) phenylene vinylene). Another process involves treatment of the bis chlormethyl dimethyl aniline hydrochloride derivative with alkali metal alkoxide.
