Patent ID: 7005460

Claim:
A multi-component system for making impressions which contains (a) at least one compound having at least two alkenyl groups; (b) at least one organohydrogenpolysiloxane; (c) at least one hydrosilylation catalyst; characterized by containing one or both of components (d 1 ) and (d 2 ), wherein (d 1 ) is wherein n=7 to 6000, R 1 =alkyl, aryl, arylalkyl, halogen-substituted alkyl or aryl groups, cyanoalkyl, cycloalkyl, —H, alkoxy, acyl and combinations thereof; R 3 =halogen, aryl, alkylaryl, H, halogen-substituted alkyl and aryl groups, alkyl, or combinations thereof; R 4 =R 3 , or R 4 is different from R 3 , wherein R 4 is alkyl, methyl, or combinations thereof; and R 5 =H, alkyl, aryl, alkylaryl, halogen, halogen-substituted alkyl and aryl groups, —OR, aminoalkyl, epoxy, cyanoalkyl, cycloalkyl, methacrylate, acrylate, mercaptoalkyl, carboxylate, carboxyalkyl or succinic anhydride, and compound (d 2 ) is wherein n=7 to 6000, R=H, alkyl, alkoxyalkyl or R 1 =alkyl, aryl, arylalkyl, halogen-substituted alkyl or aryl groups, cyanoalkyl, cycloalkyl, —H, alkoxy, acyl, or combinations thereof; R 3 =alkenyl, alkynyl, halogen, aryl, alkylaryl, H, halogen-substituted alkyl, or aryl groups, alkyl, or combinations thereof; R 4 =R 3 , or R 4 is alkyl, methyl, alkynyl, ethynyl, or combinations thereof; and R 5 =—C≡C—R 1 , H, alkyl, aryl, alkylaryl, halogen, halogen-substituted alkyl and aryl groups, aminoalkyl, epoxy, cyanoalkyl, cycloalkyl, alkylhydroxyl, methacrylate, acrylate, mercaptoalkyl, carboxylate, carboxyalkyl or succinic anhydride; and when a compound (d 2 ) having an SiOR structural unit is contained, (e) at least one condensation catalyst or condensation cross-linking agent.
