  In a polyester production method, a titanium compound having a radical selected from a carbonyl group, a carboxyl group, or an ester group, and a phosphorous compound having a structure illustrated in Formula (I), are added. 1 This yields a polyester composition which does not exhibit increased filter pressure when forming, which has excellent filament and film forming properties, and which has a polymer color tone superb to that of conventional products.

  在一种聚酯生产方法中，添加一种具有来自羰基团、羧基团或酯基团的基团的钛化合物和一种具有如公式（I）所示结构的磷化合物。这产生了一种聚酯组合物，其在成型时不会表现出增加的过滤器压力，具有优异的纤维和薄膜成型性能，并且具有比传统产品更好的聚合物颜色色调。

  Since the majority of conventional organic/inorganic composite materials are obtained by mechanical blending of a silsesquioxane and an organic polymer or other means, it was extremely difficult to control the structure of the composite as a molecular agglomerate. In order to solve such a problem, the invention is to provide a silicon compound represented by Formula (1). This novel silicon compound has a living radical polymerization initiating ability for addition polymerizable monomers of a wide range. In Formula (1), R1 is hydrogen, an alkyl, an aryl, or an arylalkyl; R2 is an alkyl, phenyl, or cyclohexyl; and A is a group having a polymerization initiating ability for addition polymerizable monomers.
