摘要

为研究POSS参与聚合反应的反应动力学

以MA

7iBu

-POSS和MMA 的本体聚合反应为研究对象

采用称重法测定转化率

得到转化率曲线以及各单体用量对反应速率的影响。结果得出:反应速率随着温度和引发剂浓度的增加而增加

随MMA质量的增加而降低

而MA

7iBu

-POSS对反应速率的影响是先增大后减小

且存在一个拐点

。另外

得到聚合反应的活化能

a=87.297kJ/mol;反应级数(引发剂)

=0.617

当MA

7iBu

-POSS的浓度

小于0.1239mol/L

7iBu

-POSS 的反应级数

=0.217

当

大于0.1239mol/L

=-0.202;同时

得出竞聚率

(MMA)=1.212

(MA

7iBu

-POSS)=0.567

由此得出

MMA 的自聚大于共聚

7iBu

-POSS的共聚大于自聚

二者在聚合物中的分布情况为无规分布。

Abstract

In this paper

in order to study the polymerization kinetics involving POSS

the polymerization reaction of MMA and Methacrylolsobutyl POSS (MA

7iBu

-POSS) was carried out. The conversion curves and the influence curves of the monomer amount on the reaction rate were obtained by weighing method. The results showed that the reaction rate of polymerization reaction increased with the increase of temperature and initiator concentration

and decreased with MMA mass increases. The influence of MA

7iBu

-POSS on the reaction rate firstly increased and then decreased

and there was an inflection point A. In addition

the activation energy of the polymerization reaction

a=87.297kJ/mol. The reaction order I(Initiator)=0.617

and n (MA

7iBu

-POSS)=0.217 when

was bigger than 0.1239mol/L and

(MA

7iBu

-POSS)= -0.202 when the concentration of

was bigger than 0.1239mol/L. Meanwhile

the reactivity ratio

(MMA)=1.212 and

(MA

7iBu

-POSS)=0.567. Thus

the self-polymerization rate of MMA was bigger than its copolymerization

and the copolymerization rate of MA

7iBu

-POSS was bigger than its self-polymerization. The distribution of the two polymerized monomers in the polymer was random.
