  有机磷化合物反应中的结构效应。一，三氯氧磷与受阻酚的反应

  摘要：

  除非烷基取代基是大体积的（即叔丁基），否则2，6-二烷基苯酚与磷酰氯的反应几乎没有空间位阻。在存在大量取代基的情况下，只有在邻位烷基脱烷基或重排，然后进行O-磷酸化后，才在Friedel-Crafts型催化剂存在下与磷酰氯发生反应。

  A plastic molded product of olefin (co)polymer composition comprises 0.01 - 5.0 weight parts high molecular weight polyethylene with an intrinsic viscosity ηE in the range of 15 - 100dl/g measured in 135°C tetralin and preferably 100 weight parts polypropylene. The high molecular weight polyethylene has an average particle size in the range of 1 - 5000nm and is finely dispersed as fine granules in the polypropylene, so that high melt strength and high crystallization temperature are attained, enabling various molding methods to be performed with high speed productivity. Using the polymer composition, plastics such as a resin foam, a film, a sheet, a layered plastic article with a coated substrate surface, a hollow plastic article, an injection molded plastic article, a fiber, a nonwoven web or a continuous tube-shaped plastic are provided. The olefin (co)polymer composition is obtained by preparing high molecular weight polyethylene granules using e.g. a titanium transition metal compound catalyst, and adding these, e.g. as a polymerization catalyst of propylene, singly or together with a polyolefin preparing catalyst.
