A cross-linkable, electrically conductive composition comprising (a) a soluble, electrically conducting polymer having a sulfonic acid group and/or a carboxyl group and (b) a thermally cross-linkable or ultraviolet- or electron beam-cross-linkable resin or paint.

Cross-linkable, electrically conductive composition, electric conductor

A method for recovering an uncrosslinked synthetic resin waste including dissolving the uncrosslinked synthetic resin waste in a solvent containing, as an active ingredient, one or more oxyisobutyric acid esters selected from an alkyl .alpha.-alkoxyisobutyrate, an alkyl .beta.-alkoxyisobutyrate and an alkyl .alpha.-hydroxyisobutyrate. This invention provides a method for recovering a plastic waste by using a highly safe solvent which is free from the problems encountered in the conventional methods with the use of aromatic hydrocarbons or halogenated hydrocarbons, and comprises non-halogen solvents, forms no substance causing environmental problems, has a high ability to dissolve plastic wastes, has neither toxicity nor any offensive odor, is not accumulated in nature because of its high biodegradability, and has a relatively high boiling point.

Method for recovering uncrosslinked synthetic resin waste

A solvent composition containing at least one of an alkyl .alpha.-alkoxyisobutyrate, an alkyl .beta.-alkoxyisobutyrate, and an alkyl .alpha.-hydroxyisobutyrate as an active component is disclosed. The solvent composition is of low toxicity and harmless to humans, has an extremely high dissolving power for high polymers, fats and oils, fluxes, liquid crystals, etc., produces no environment destructive substance, gives off no offensive odor, and has a relatively high boiling point indicative of safety and ease in handling.
