粘度法研究氯化聚丙烯和涂料树脂间的相容性
Study on the Miscibility of Chlorinated Polypropylene with Coating Resins by Viscometry
摘要
Abstract
The viscosities of the dilute solutions containing chlorinated polypropylene(CPP)and the coating resins,such as petroleum resin (PTR ), acrylic resin (ALR ) and alkyd resin (SAR ), with different compositions were measured. The miscibilities of PTR/CPP blends,ALR/CPP blends and SAR/CPP blends were discriminated by the miscibility criterion α which was calculated from the experimental data by dilute solution viscosity. The results show that PTR/CPP blends are miscible and ALR/CPP blends are immiscible, while the miscibilities of SAR/CPP blends are determined by their compositions. SAR/CPP blends are compatible when the mass ratios of SAR to CPP are less than 1:1 ,while the blends are incompatible when the mass ratios are greater than 1:1,which are consistent with the results of the stability of the mixtures,the clarity and the related glossiness of the films. Therefore,the dilute solution viscosity can be used in the determination of coating polyblend miscibility by determining polymer-polymer interactions in solution.关键词
