Abstract: Hair care compositions contain from 0.1 to 12 weight percent of a silicone copolymer or saponification product thereof, prepared from silicones, at least 10% of which contain polymerizable groups, 0.5-14% of hydrophilic comonomers, and 30-99.9% of hydrophobic comonomers. The compositions exhibit good hair care properties.

Abstract: The invention provides a chewing gum base containing a homogeneous composition in solid form comprising a) from 50 to 90% by weight of polyvinyl acetate and b) from 10 to 50% by weight of vinyl acetate-vinyl laurate copolymer, the weight percentage based on the total weight of the composition.

Abstract: Polymer dispersions of polymers derived from silicone macromers and ethylenically unsaturated monomers are capable of incorporating large amounts of chemically bonded macromer, when the silicone macromer and part of the unsaturated monomer are polymerized in aqueous medium as an initial charge with an oil soluble initiator, and the remaining monomers are fed in and polymerized using a water soluble initiator. The dispersions may be dried to form water redispersible polymer powders.

Abstract: Silicone-containing addition polymers having numerous uses are prepared by polymerizing addition polymerizable monomers in the presence of a silicone-containing polyvinyl alcohol, and/or by adding a silicone-containing polyvinyl alcohol to an aqueous addition polymer dispersion prior to spray drying, the silicone-containing polyvinyl alcohol containing at least one polymerizable group.

Abstract: Silane-modified polyvinyl acetals are obtained by copolymerizing a) vinyl esters of C1-15 alkylcarboxylic acids having from 1 to 15 carbon atoms, and optionally (meth)acrylates C1-15 of alcohols, olefins, dienes, vinylaromatics, or vinyl halides, with b) from 0.02 to 20.0 % by weight of an ethylenically unsaturated, hydrolyzable silicon compounds or hydrolyzable mercaptosilanes; hydrolyzing the resulting vinyl ester copolymers to 50 mol % or more of vinyl alcohol units; and acetalizing vinyl alcohol units with a C1-15 aliphatic or aromatic aldehydes, wherein from 5 to 50 % by weight of a mixture of comonomers a) and silane comonomers b), based on the total weight of comonomers a) and b), is used as an initial charge, and the remainder is metered in during polymerization, such that the ratio between the comonomers a) and silane comonomers b) remains constant throughout the polymerization, resulting in a homogeneous polymer.
