摘要

开发一种杨木改性新方法:先采用琥珀酸酐（SA）预处理杨木,然后分别采用苯乙烯（ST）单体、苯乙烯-甲基丙烯酸缩水甘油酯（ST-GMA）对其进行原位聚合改性。检测结果显示,SA预处理试样仅尺寸稳定性有一定程度的改善,再经过ST、ST-GMA原位聚合改性后,试样的尺寸稳定性、力学性能和防腐能力均显著提高。

Abstract

The authors studies poplar wood samples following pretreatment,first with succinic anhydride（SA） and then modifying them with styrene（ST） monomer and succinic anhydride-glycidyl methacrylate（ST-GMA） using in situ polymerization to improve their dimensional stability,mechanical properties,and durability.The results showed that the dimensional stability of samples treated with SA improved considerably and the dimensional stability,mechanical properties,and decay resistance of samples modified with ST and ST-GMA showed considerable improvement.
