20080196824 | Coloured Polymers System with Improved Colour Brilliance - A process for improving the color brilliance of a color polymer system which is composed of a matrix and discrete polymer particles which are distributed in the matrix in accordance with a defined spatial lattice structure and are obtained by filming an emulsion polymer with core/shell structure, the emulsion polymer being obtainable by polymerization of monomers in at least one first stage (monomers of the core) and subsequent polymerization of monomers in at least one further, second stage (monomers of the shell), which comprises polymerizing the monomers of the core in the presence of an absorber for electromagnetic waves especially a UV absorber. | 08-21-2008 |
20080242790 | Aqueous Polymer Dispersions Containing Amphiphilic Block Copolymers, Method for Producing Said Dispersions and the Use Thereof - The invention relates to aqueous polymer dispersions, obtained by the emulsion polymerisation of ethylenically unsaturated monomers in an aqueous medium in the presence of polymerisation initiators and stabilisers that form radicals. According to the invention, amphiphilic polymers are used as stabilisers prior to, during or after polymerisation, said polymers containing one or more hydrophobic units (A) and one or more hydrophilic units (B), the hydrophobic units (A) being formed from a polyisobutene block, wherein at least 50 mol % of the polyisobutene macro-molecules have terminal double bonds. The invention also relates to a method for producing the aqueous polymer dispersions by the polymerisation of ethylenically unsaturated monomers in the presence of initiators that form radicals and the aforementioned amphiphilic polymers, which are used prior to, during or after polymerisation. The invention further relates to the use of the aqueous polymer dispersions that are obtained in this manner as associative thickeners in coating slip for paper, in the production of textiles, as thickening agents for textile printing pastes, in the pharmaceutical and cosmetic industry, for paints, for detergents and cleaning agents, in foodstuffs and as oilfield chemicals. | 10-02-2008 |
