| Abstract: | Based on the problem of high ash content in 1102K of polypropylene homopolymer,source of the ash and the theoretic calculation value were analyzed.To reduce the ash in the products followingmethods were implemented,impurities in the propylene decreased by refining perfectly,resulted in use level of catalyst and triethyl aluminum lessened,improvement of the production in single reactor resulted from efficient catalyst applied,and DHT-4A of hydrated talc substituted by modified halogen absorbent. |
