A composition, and a method of using the composition, are described which composition comprising: (A) at least one chlorinated polyvinyl chloride or mixture of at least one polyvinyl-chloride and at least one chlorinated polyvinyl-chloride thereof; (B) at least one volatile organic liquid which is a solvent for the polymer of (A); and (C) a stabilizer comprising (i) an organophosphite compound, at least one hindered phenol, at least one of an organotin compound or mixtures thereof, and (ii) at least one metal-containing carbonate salt. The composition and methods of the present invention act to retard the loss of chlorine from the resins of the adhesive compositions and to absorb or otherwise inactive any lost chlorine. The compositions of the invention are useful in a variety of applications including use as adhesives, cements (including solvent cements) glues or pastes for holding together materials by surface attachment, and as sealants which are load-bearing elastic jointing and insulating materials.
