PCT No. PCT/FR90/00968 Sec. 371 Date Oct. 28, 1991 Sec. 102(e) Date Oct. 28, 1991 PCT Filed Dec. 28, 1990 PCT Pub. No. WO91/09884 PCT Pub. Date Jul. 11, 1991.The present invention relates to functionalized chlorinated (co)polymers and methods for their preparation. The functionalization is performed with an organometallic compound where the metal may be tin, lead, antimony or bismuth. The organic groups are hydrocarbons which may be substituted and one group is either a secondary amine or an ether which is eventually substituted by a trialkoxysilane or a hydroxy group. The preferred chlorinated polymer is PVC and the preferred functionalizing agent is an organotin compound.
