Abstract
A method for preparation of organopolysiloxanes suitable for use as binders in hardenable compositions of polymerizable monomers, the organopolysiloxanes being modified with methacrylic esters by reacting --COH-group containing methacrylic esters with organopolysiloxanes containing --SiX groups wherein X is alkoxyl, hydroxyl or chloro and wherein the organopolysiloxanes are reacted from 0.05 to equimolar amounts of pentaerythritol trimethacrylate. The organopolysiloxanes of the present invention exhibit rapid hardening properties under curing conditions. The compounds and compositions obtained with this process are also disclosed.
