Abstract: A conductive polymer comprises a silicon-containing polymer having, in the main chain thereof, Si--Si bonds or both Si--Si bonds and C--C multiple bonds, and ferric chloride doped in said polymer through vapor phase doping. A method for preparing such a conductive polymer is also described.

Abstract: A polysilane having an aromatic amino group is doped with an oxidative dopant, typically iodine and ferric chloride, to produce a highly conductive polysilane composition having improved shapability. The composition is easily applicable to form a highly conductive film or coating.

Abstract: An epoxy resin composition comprising (i) an epoxy resin, (ii) a phenolic curing agent, (iii) an organophosphorous curing agent, (iv) alumina, and (v) a separating means for separating the organophosphorous curing agent and the alumina, which may be a coating over the surfaces of the organophosphorous curing agent.

Abstract: A UV curable composition of a specific organopolysiloxane having mercaptoalkyl and phenylene groups and a vinyl-containing organopolysiloxane cures into a film which emits little stimulative sulfur odor and has enough resistance to light or UV radiation to retain its as-cured properties even after long-term exposure to sunlight or UV radiation.

Abstract: Novel organosilicon compounds containing a mercapto group are provided, which compounds are of the following general formula, HSCH.sub.2 C.sub.6 H.sub.4 (CH.sub.2).sub.n Si(CH.sub.3).sub.3-m (OR).sub.m, wherein R represents a methyl group or an ethyl group, n is a value of 0,1 or 2, and m is a value or 1, 2 or 3. the ocmpounds are substantially free of any offensive odor derived from the mercapto group and are useful as a silane coupling or crosslinking agent.

Abstract: Provided herein is an ultraviolet-curable gel composition which comprises an organopolysiloxane as a principal component which is represented by the general structural formula below. ##STR1## where R.sup.1 is a C.sub.4-25 monovalent organic group containing therein 1 to 2 vinyl functional groups; R.sup.2 is a C.sub.1-18 monovalent organic group having no vinyl group capable of addition polymerization; R.sup.3 is a C.sub.2-4 divalent hydrocarbon group; R.sup.4 is a C.sub.1-9 substituted or unsubstituted hydrocarbon group of the same or different kind; a is an integer of 1 to 3; and n is an integer of 5 to 500.
