    摘要: The invention relates to a process for free-radically initiated heterophase polymerization, in which the polymerization of ethylenically monomers proceeds in a phase dispersed in the continuous phase, characterized in that one or more additives which are soluble in the continuous phase and insoluble in the disperse phase and stop the polymerization of the ethylenically unsaturated monomers in the continuous phase is/are added before or during the polymerization.

    摘要: Polymer blends containing polymers or low molecular weight compounds containing groups of the formula ≡Si—O—C(R1)(R2)(R3) where R1, R2, and R3 are hydrogen, halogen, or an organic radical, not more than two of which are hydrogen, may be cured thermally or photochemically to produce solvent resistant polymers. The curing may take place in the absence of water.
