A curable polymer composition comprising (a) an oxyalkylene polymer having a silicon-containing group which has a hydroxyl or hydrolyzable group bonded to the silicon atom and is cross-linkable through silanol condensation and (b) a paraffin hydrocarbon, optionnaly together with (c) a silicone compound having a long-chain hydrocarbon group. The composition provides cured products reduced in the tack remaining on the surfaces.
L'invention concerne une composition polymère durcissante comprenant (a) un polymère oxyalkylène ayant un groupe contenant du silicium et comprenant un groupe hydroxyle ou un groupe hydrolysable fixé à l'atome de silicium et capable de subir une réaction de réticulation par une condensation impliquant du silanol, (b) un hydrocarbure paraffinique, et éventuellement (c), un composé silicone ayant une chaîne hydrocarbure longue. La composition permet de produire des produits qui, après durcissement, présentent des surfaces peu collantes.
