The Research of Plasma Induced Polymerization of(2-Methacryloyloxyethyl) Thrimethyl Ammonium Chloride

研究了等离子体引发聚合2-甲基丙烯酰氧乙基三甲基氯化铵（DMC）．测定了不同放电时间与放电功率时反应室温度的变化方程，发现反应室温度变化是影响聚合产物P（DMC）性质的主要因素之一。反应室温度低于130℃．P（DMC）为线性。最高特性黏数为420．2cm^3／g，反应室温度为130℃～200℃，P（DMC）为交联性吸水树脂。吸水率为15g／g．优化了线性产物的反应条件：放电时间60s，放电功率60w，此时反应室温度为80℃。并经计算验证了等离子体引发聚合DMC理论可行．

Plasma induced polymerization of （2-methacryloyloxyethyl） thrimethyl ammonium chloride was studied . The effects of discharge time, discharge power and pressure on reactor temperature were measured. In this paper, the change of temperature in reactor which influenced properties of P（DMC） was also investigated. The result shows that when the reactor temperature is lower than 130 ℃, P（DMC） is linear, and the highest intrinsic viscosity of P（DMC） can be 420. 2 cm^3/g, when reactor temperature is more than 130 ℃, P（DMC） is crosslinked, and the rate of absorbing water of P（DMC） is 15 g/g. The polymerization condition of linear P（DMC） are optimized as follows： discharge time 60 s, discharge power 60 W, reactor temperature 80℃. Moreover, the calculated result identified that plasma induced polymerization of （2-methacryloy- loxyethyl） thrimethyl ammonium chloride was feasible in theory.
