Abstract

To make a base polymer of a new soft resin material, a copolymer of 1,3-Bis(methacryloxypropyl)tetramethyl disiloxane (BMPMS) and methyl methacrylate monomer (MMA) was investigated. It was found that the compressive strength, bending strength and bending modulus value of the copolymer decreased with increase in BMPMS concentration. While, transverse deflection increased with increase in BMPMS concentration. As for the 50% inhibitory concentration value, it was about 0.8 mM for BMPMS.

摘要

为制备一种新型软质树脂材料的基础聚合物，对1,3-双（甲基丙烯酰氧基丙基）四甲基二硅氧烷（BMPMS）与甲基丙烯酸甲酯单体（MMA）的共聚物进行了研究。发现该共聚物的抗压强度、抗弯强度和弯曲模量值随BMPMS浓度的增加而降低。而横向挠度随BMPMS浓度的增加而增加。至于50%抑制浓度值，BMPMS约为0.8 mM。
