摘要

以甲基丙烯酸缩水甘油酯(GMA)为单体

乙二醇二甲基丙烯酸酯(EGDMA)为交联剂

聚乙烯醇(PVA)为分散剂

偶氮二异丁腈(AIBN)为引发剂

采用悬浮聚合法制备了粒径可控的以GMA为主单体的二元共聚物交联微球PGMA.考察了分散剂用量、搅拌速度、水油相比例、交联剂用量、NaCl用量等因素对成球性能、微球粒径的影响规律

并确定了成球最佳条件.采用红外光谱(FTIR)表征了微球的化学结构

使用扫描电子显微镜(SEM)观察了微球的形貌.研究结果表明:在水介质中加入电解质NaCl

采用悬浮聚合法并通过控制各反应条件

可以制备出球形度极好、粒径在60~180μm范围内的交联微球PGMA.

Abstract

The crosslinking microbeads PGMA with controllable size were synthesized by suspension polymerization of glycidyl methacrylate(GMA) and ethylene glycol dimethylacrylate(EGDMA).The chemical structure and morphology of PGMA were characterized with FT-IR spectrum and SEM respectively.The effects of various factors

such as disperser PVA weight percentage(wt%)

agitating rate

the ratio of oil phase to water phase

the weight percentage(wt%) of EGDMA and NaCl

influence law of sphericity and diameter of the microbeads were examined.The experimental results show that the sphericity of crosslinking microsbeads PGMA is excellent and various factors above-mentioned can all influence the particle diameter.In order to prepare PGMA microsbeads with the diameter about 100 μm

the optimal condition is achieved.
