摘要
主要针对降低PMMA吸水率的要求,运用分子设计原理用苯乙烯、N-苯基马来酰亚胺进行PMMA共聚,并对其制备工艺进行改进,得到吸水率降低30%左右、力学性能变化不大、800 nm透光率可达90%的PMMA共聚物。
PMMA of low water absorptivity was copolymerized with styrene and PMI using molecule design principle and the preparation craft was improved. The experiment results showed that the water absorption of PMMA was reduced about 30 %, the mechanics performance changed a little, and light transmittance of PMMA copolymer at 800 nm reached to 90 %.
