摘要

在聚丙烯小球水悬浮液中以过氧化二苯甲酰 (BPO)为引发剂

利用水悬浮液沸点下的沸腾搅拌效应制备了接枝率为 9.0 6 %的马来酸酐 (MAH)接枝聚丙烯 (MAH - g -PP)小球 .用正交实验考察了反应时间、MAH及BPO用量对接枝率的影响规律

并用红外光谱对MAH -g -PP接枝共聚物进行了表征 .吸附实验结果进一步表明

与未接枝PP相比

MAH - g -PP对极性物质如水、Cu2 + 、染料、糖化酶的亲合力大为提高 .

Abstract

Initiated by bi-benzoyl peroxide (BPO)

maleic anhydride (MAH) was grafted onto the surfaces of polypropylene (PP) beads

swelled with a small amount of toluene

at the boiling point of a self-stirring water suspension system. The influences of reaction time and the dosage of MAH and BPO on graft degree of the copolymer were investigated by orthogonal experiments. Under the chosen optimal condition of 120ml water

10 ml toluene

0 3g BPO

8 0g MAH and 20 0g PP reacted through circumfluence for 4 5h at the boiling point 102℃

MAH grafted PP (MAH- g-PP ) with a graft degree 9 06% was obtained and it’s graft status was characterized by FTIR spectra. The results from a series of adsorption experiments demonstrated that MAH- g-PP showed much more affinities to polar substances like water

Cu 2+

dyestuff and glucoamylase in comparison with the affinities of PP

and revealed the promise future of its wide application in solubilizers for PP alloys

ionic exchange resins

antibacterial materials

medicine carriers and enzyme supports etc. The titled method has outstanding advantages in process controls and post treatment.
