苯乙烯—甲基丙烯酸甲酯共聚物的物理性能测试

Determination of physical performance of styrene-methyl methacrylate copolymer

对小试和中试所得的苯乙烯(ST)甲基丙烯酸甲酯(MMA)共聚物珠粒进行了分子量、密度、粒度分布和单体残留量的测定,说明熟化温度将影响共聚物的物理性能,为进一步工业化提供了可靠的实验数据和理论依据.

The molecular weight, density, distribution of bead degree and residual quantity of monomer of the copolymer beads of styrene（ ST）- methyl methacrylate（MMA） were determinated by small and middle size experiments. It is shown that physical performance of copolymer is deeply influenced by reaction temperature, providing dependable experiment data and theoretical foundation for further industrialization.
