摘要:
The object of the invention are methods for producing composite particles, characterized in that α) one or more silicon compounds of the general formula: (RO)nSiR14-n (1), wherein R denotes an optionally substituted alkyl or aryl residue having 1 to 20 carbon atoms or a hydrogen atom, R1 denotes an optionally substituted hydrocarbon residue or a hydrogen atom, and n assumes a value of 1 to 4, or β) one or more condensation products of the silicon compounds of formula (1) are condensed in the presence of one or more soluble polymers in a solvent or a mixture of multiple solvents, wherein said soluble polymers are obtainable by radically initiated polymerization of a) one or more ethylenic unsaturated monomers having one or more further functional group selected from the group comprising carboxyl groups or the derivatives thereof, silane, sulfonic acid, sulfate, phosphate, phosphonate, isocyanate, amine, quaternized amine, hydrazine, epoxy, ether, hydroxyl, or CO groups, and b) one or more ethylenic unsaturated monomers selected from the group comprising vinyl esters of carboxylic acids having 1 to 15 C atoms, methacryclic acid esters or acrylic acid esters of carboxylic acids with branched or unbranched alcohols having 1 to 15 C atoms, olefins and dienes, vinyl aromatics and vinyl halides, and wherein condensation products thus formed of said silicon compounds α) or condensation products β) or the condensation products thereof are fixed on one or more soluble polymers.

摘要:
The invention discloses a method of using crosslinkable polymer powders for producing ballistic-resistant fiber materials, which comprises consolidating the textile sheet materials by means of pulverulent crosslinkable copolymers which are based on ethylenically unsaturated monomers and have a glass transition temperature Tg or a melting point of ≧40° C. and a melt viscosity of ≧2000 mPas.
摘要:
A composition is described containing fine solid particles held in an encapsulation or dispersed in a matrix and which are inert towards the encapsulation or the matrix, whereby the encapsulation or the matrix consists of a homogeneous mixture of cellulose, tertiary amine oxide, water and, if necessary, other components. The compositions are suited for matting, pigmenting etc. of cellulose filaments, films and membranes.
