【摘要】 本文提出了氯乙烯-乙酸乙烯酯共聚物组成的简化计算法,作出了配比为0.84—0.96克分子分数氯乙烯时的共聚物组成算图和组成分布图。如果对共聚物组成均一性的要求不十分严格,含82—95％（重量）氯乙烯的共聚物可以由一次投料法来生产。简化计算法可以推广于r₁>1、r₂<1而以单体1为主的共聚物组成的计算。更多还原

【Abstract】 A simplified method for calculating the composition of vinyl chloride-vinyl acetate copolymers has been proposed in this paper. The composition nomogram and the composition distribution diagram of the copolymer containing 0.84-0.96 mole fraction of vinyl chloride have been constructed. If strict uniformity in the composition of the copolymer is not required, the copolymer containing 85-95% vinyl chloride by weight may be manufactured by the once-charge method. The simplified method may be extended to compute the composition of other copolymer systems with γ1> 1, γ2 < 1 in which the monomer M1 is the main component.更多还原
