发明名称 A method for preparing a vinyl polymer-polyolefine composite.
摘要 <p>A method for preparing a polyolefine - vinyl polymer composite in which a) 10-200 weight fractions of vinyl monomer and 0.01-4.0 weight fractions, based on 100 weight fractions of vinyl monomer, of a free radical polymerisation initiator are impregnated into 100 weight fractions of polyolefine particles by blending these at a temperature of 20-100 DEG C, while continuously or discontinuously adding 1-60% by weight of water based on the total weight of the vinyl monomer and the polyolefine, during the maintenance of the particle structure of the polyolefine; b) a water suspension is prepared by adding to the above-mentioned mixture after a completed impregnation suspension water, whereby the total quantity of water becomes 80-1000 weight fractions, based on 100 weight fractions of polyolefine and vinyl monomer, as well as a stabilising agent; c) the temperature of the water suspension is increased to polymerise the vinyl monomer. </p>
