CROSSLINKABLE AND REDISPERGABLE DISPERS POWDERS CONTAINING VINYL-ESTHER- OR (MET)ACRYL-ESTHER-COPOLYMERS AND PROCESS FOR USING SUCH POWDERS

摘要

(57) EXECUTIVE SUMMARY The dispersible spores of the present invention are one or more vinyl esters of vinyl esters of straight or branched chain alkanecarboxylic acids having 1 to 15 carbon atoms as an artificial sea, or one or more alkyl or alkyl esters of 1 to 10 carbon atoms. acrylic acid and / or methacrylic acid ester rock polymerization needles prepared from methacrylic acid esters as artificial sea and 0.1 to 10% by weight, based on the total weight of the rock polymer, of one or more double-bonded crosslinking amide or ether types contain a quarry. The dispersion stakes according to the invention are used for the production of wood, cellulose, wool, wool, mineral fibers, ceramic fibers, man-made fibers based on fiber-forming polymers, carbon fibers and thermal or rock-based base stimuli of vinyl chloride or tetrafluoride. Fiber-reinforcement is carried out by spraying 5 to 50% by weight of dispersion powder, based on the weight of the fibrous material, onto or, if necessary, shaking it into the reinforced fibrous material or mixing it directly with the fibers which are still dispersed by mechanical means. Before or after the powder is wetted, it is moistened by spraying with 5 to 60 m% of water, based on the dry weight of the mixture of fibers and binder, and then heated to 100 øC to 200 øC on a fiber opener. ŕ
