| 摘要 |
The invention relates to cross-linkable compositions containing: (A) organopolysiloxanes comprising alkenyl groups, of general formula (I), wherein R represents a monovalent, SiC-bonded, optionally substituted hydrocarbon radical which contains between 1 and 18 hydrocarbon atoms and is free of aliphatic carbon-carbon double bonds, R1 represents a monovalent SiC-bonded, optionally substituted hydrocarbon radical comprising between 1 and 19 hydrocarbon atoms, A represents an allyl radical, Vi represents a vinyl radical, m represents a value of between 40 and 1000, and n represents a value of between 1 and 10; (B) organosilicon compounds containing Si-bonded hydrogen atoms; and (C) catalysts favouring the addition of Si-bonded hydrogen to aliphatic double bonds.
