    • A process for the production of modified polymers, preferable in organic solvents, by radical-initiated polymerization of(Ia) 70 to 99.9 parts by weight of esters of the formulaCH.sub.2 .dbd.C(R)--COOR' (Ia) in which R is --H or --CH.sub.3 and R' are 1 to 18 C-alkyl radicals, at least 50% by weight of the esters of (Ia) being those in which R' are 1 to 4 C-alkyl radicals,(Ib) 0, 1 to 20 parts by weight of .omega.-hydroxyalkyl esters of acrylic, methacrylic, maleic and/or fumaric esters, the said dicarboxylic acids are possibly etherified on the second carboxylic group with 1 to 12 C-atoms containing alcohols and(Ic) 0 to 10 parts by weight of other unsaturated monomers, the sum of (Ia), (Ib) and (Ic) amounting to 100 parts by weight, in the presence of(II) 5 to 40 parts by weight of terminal blocked alkyl-hydrogen polysiloxanes, the alkyl radicals containing 1 to 4 carbon atoms, with a viscosity of 20 to 1000 cP at 20.degree. C., the ratio of alkyl radicals to hydrogen atoms thereof being from 13 : 1 to 1 : 1, in which ratios the terminal groups are not included. Organic solvents containing the obtained modified polymers and usual curing agents for alkyl-hydrogen polysiloxanes are useful for treating fibrous material to give water-tight and water-repellent effects.

    • While good oil-repellency can be imparted to fibre materials by treating them with polymers containing perfluoralkyl groups, it is difficult to impart water-repellency to the fibre materials at the same time and also give the treated materials a good handle. This is achieved by treating the fibre materials with, besides the perfluoralkyl group-containing polymers, an addition product of a) an unsaturated compound which is an olefin, a vinyl or allyl ester of an aliphatic straight or branched chain acid, a vinyl ether whose alkyl radical has at least 4 carbon atoms, an allyl ether whose alkyl radical has at least 4 carbon atoms and/or a vinyl halide with b) an organopolysiloxane which contains hydrogen atoms bonded to silicon atoms, the addition product containing on average more than 7 carbon atoms in the alkyl radical and at least 0.20 mole of the unsaturated component a) per gram atom of hydrogen in the siloxane component b).
    • 通过用含有全氟烷基的聚合物处理纤维材料,可以赋予纤维材料良好的拒油性,难以同时赋予纤维材料防水性,并且也使处理过的材料具有良好的手感。 这是通过除含全氟烷基的聚合物以外处理纤维材料来实现的,该加成产物是a)不饱和化合物,其是烯烃,脂族直链或支链酸的乙烯基或烯丙酯,乙烯基醚, 烷基具有至少4个碳原子,其烷基具有至少4个碳原子的烯丙基醚和/或乙烯基卤化物,以及b)含有与硅原子键合的氢原子的有机聚硅氧烷,该加成产物平均含有7个以上 烷基中的碳原子和至少0.20摩尔不饱和组分a)在硅氧烷组分b)中每克原子的氢。
