| 摘要 |
The invention relates to compositions which crosslink to give elastomers, containing (1) a diorganopolysiloxane containing condensable terminal groups which contains a copolymer of monomers containing aliphatic multiple bonds, preferably styrene and n-butyl acrylate which has been produced by copolymerisation of monomers containing aliphatic multiple bonds, preferably styrene and n-butyl acrylate, by means of free radicals in the presence of diorganopolysiloxane, (2) a silane of the formula RxSi(OR<1>)4-x where R and R<1> are as defined in Claim 1, and x is 0 or 1, or an oligomer thereof, and (3) a phosphoric ester (phosphate) of the formula <IMAGE> where R<2> is hydrogen or a readily removable radical, the radicals R<3> are identical or different and are a monovalent hydrocarbon radical, which is optionally halogenated and/or interrupted by one or more groups of the formulae -O-, -S-, -C(O)O-, -N=, -NR<5>- and -SiR2-, or is a readily removable radical, or both radicals R<3> together are a divalent hydrocarbon radical and R<5> is as defined in Claim 1. |
