    • A method for preparing a polyolefine-vinyl composite, in which method about 10-200 weight fractions of vinyl monomer and about 0.01-4.0 weight fractions of a free radical polymerization initiator, based on 100 weight fractions of vinyl monomer, are impregnated in 100 weight fractions of polyolefine particles by slowly mixing these at a temperature of about 20.degree.-100.degree. C. while continuously or discontinuously adding about 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, is disclosed. A water suspension is prepared by adding water and stabilizing agents to the above-mentioned mixture after a completed impregnation. The total quantity of water is about 80-1000 weight fractions, based on 100 weight fractions of polyolefine+vinyl monomer. The temperature of the water suspension is then increased for polymerizing the vinyl monomer.
    • 一种制备聚烯烃 - 乙烯基复合材料的方法,其中基于100重量份乙烯基单体约10-200重量份的乙烯基单体和约0.01-4.0重量份的自由基聚合引发剂以100重量份 通过在约20℃-100℃的温度下缓慢混合它们,同时连续地或不连续地加入约1-60重量%的水,基于乙烯基单体和聚烯烃的总重量,聚烯烃微粒的分数 公开了维持聚烯烃的颗粒结构。 在完全浸渍之后,通过向上述混合物中加入水和稳定剂来制备水悬浮液。 基于100重量份的聚烯烃+乙烯基单体,水的总量为约80-1000重量份。 然后增加水悬浮液的温度以使乙烯基单体聚合。
