A stable microemulsion of Chinese lacquer ( MECL) was prepared with a phase inversion by blending the polymer emulsions of polyvinyl formal ( PVFM) and styrene-acrylate copolymer ( SA).
以聚乙烯醇缩甲醛和苯乙烯-丙烯酸酯共聚物为乳化剂，通过相反转方法直接微乳化生漆。
Research and Application of PVFM Foam Plastics
PVFM泡沫塑料的研究及应用
The results showed that PVFM foam was not sufficient homogeneous on the basis of the data discreteness of the mechanical properties;
结果表明：①根据力学性能数据的分散性，PVFM泡沫材料质地上是不够均匀的；
The decrease of the mechanical properties were caused by the PVFM hygroscopicity;
力学性能的下降是由于材料的吸湿性引起的；
PVFM hydrogel shows rather fast swelling/ deswelling rate, and its mechanical behavior is sensitive to the change of water content, as a result the flow rate is modulated accordingly.
结果表明，多孔聚乙烯醇缩甲醛凝胶具有很快的吸水/脱水速度和膨胀应力变化的灵敏响应性。
