    Abstract: Adhesives comprising polyvinyl ether copolymers having a weight-average molecular weight > 10,000, which are composed of a) from 0 to 95% by weight of vinyl ethers of the formula I H2C = CH-O-R, b) from 5 to 100% by weight of hydrophilic vinyl ethers of the formula II H2C = CH-O-R , and c) from 0 to 30% by weight of further monomers, in which R is a C1-C10-alkyl group and R1 is an aliphatic or cycloaliphatic radical which may be substituted by hydroxyl groups or interrupted by nonadjacent groups -Y-, where Y is an oxygen atom, a sulphur atom, a group NR or N R R X , in which R and R independently of one another are a hydrogen atom or a C1-C4-alkyl group, and X is a counteranion, and the molar ratio of carbon atoms to the sum of groups Y and hydroxyl groups in the aliphatic or cycloaliphatic radical is from 1.01:1 to 6.5:1.

    Abstract: Production of an aqueous polymer dispersion involves moving the reaction emulsion through an external cycle (9) leading from and returning to a reaction vessel. The cycle (9) has a shearing-deficient pump and a heat exchanger (8) having a laminar flow profile. Production of an aqueous polymer dispersion comprises radically polymerizing compounds (I) having individual solubility in water of at least 0.001 wt.%, and comprising polymer particles containing compounds (II), whose water solubility is less than 0.001 wt.%. An oil-in -water mixture (emulsion I) is produced from a mixture of compound (I) including the compounds (II). An Independent claim is also included for the apparatus used to carry out production process.

    Abstract: In a process for the preparation of homo or copolymers of at least one polymerisable monomer consisting of styrene, butadiene, vinyl chloride, vinyl acetate, vinylidene chloride, alkyl(meth)acrylate, meth(acrylic)acid, (meth)acrylonitrile or (meth)acrylamide by an emulsion polymerisation technique, reaction is carried out at at least 40 degrees C in the presence of a dispersing agent and a radical initiator such that at least 85 wt.% of the polymer is prepared by (a) mixing water, inert solvent and optionally dispersing agent and optionally a portion of the monomer, (b) adding initiator and (c) adding the rest of the monomer, optionally in the form of an emulsion with further water and optionally further dispersing agent or processing aids. Steps (a) and (b) or (b) and (c) may be carried out together at 40-120 degrees C and the resulting dispersion from each step or all the steps is recirculated around a flow loop external to the reaction vessel containing a low shear pump and a heat exchanger exhibiting a laminar flow profile. An apparatus for carrying out the reaction is also claimed and comprises means for storing and feeding reactants and processing aids, a reactor vessel with a heating/cooling mantle and means for draining, an external flow loop with a low shear pump and heat exchanger exhibiting a laminar flow profile and necessary connecting pipes.

    Abstract: The preparation of compounds of formula CH2=CH-O-X-CH2CH2SiRy(OR')3-y (I) comprises reacting divinyl ethers of formula CH2=CH-O-X-CH=CH2 (II) with silanes of formula HSiRy(OR')3-y (III) at 70 - 150 deg C in the presence of a homogeneous hydrosilation catalyst. The catalyst is a platinum or rhodium compound, and the amount of Rh or Pt is 0.05 - 10 ppm with respect to (II and (III). R, R' = 1-6C alkyl or 6-10C aryl; X = 1-20C hydrocarbon, optionally substituted by halo and/or containing O atoms; and y = 0 - 2.
