关于聚乙烯醇熔融性质的研究

本文从高分子物理的基本原理出发,通过聚乙烯醇与其它化合物(包括聚合物)的物理或化学处理,来探索聚乙烯酸纤维改性的技术途径。即在纺丝用的聚乙烯醇中加入增熔剂或别的成纤高分子,组成不同的高分子共混体系。通过差热分析热谱曲线的测定比较,研究几种不同的增熔剂和高聚物对聚乙烯醇熔融热性能的影响,探索降低聚乙烯醇熔融温度和制备稳定的聚乙烯醇熔体的基本途径,以便深入研究最终实现聚乙烯醇的熔融纺丝的新技术。

A study on the Melting Properties of the Polyvinyl Alcohol

In this paper on the basis of the theory of the high-polymer physics through chemical or Physical treatments for the polyvinyl alcohol blending with compound or other polymer, the methods of modification in the preparing and processing the polyvinyl alcohol fiber have been examined. Polyblends can be obtained by blending the polyvinyl alcohol with plas-ticizers or other polymer. Their variations of the melting properties in lowering the melting-point have been measured by the method of Differential Thermal Analysis (DTA) In futher studies, these properties can eventually establish a new process in Mlelt-Spinning.
