Plasma-Initiated Polymerization of (2-Methacryloyloxyethyl) Thrimethyl Ammonium Chloride
Plasma-initiated polymerization of (2-methacryloyloxyethyl) thrimethyl ammonium chloride (MTAC)) was studied. The effects of discharge time and discharge power on temperature in a tubular-type reactor chamber were accurately tested by on-line thermocouple, and the equation relating discharge time, discharge power and temperature in the tubular-type reactor chamber was derived. The results indicated that temperature played a very important role in controlling the solubility of Poly(MTAC) in water. For T \ge 130°, Poly(MTAC) was cross-linked, and the highest rate of absorbing water of Poly(MTAC) was 15 g · g-1. For T < 130°, Poly(MTAC) was linear, and the highest intrinsic viscosity of Poly(MTAC) was 420.2 cm3 · g-1. The polymerization condition of linear Poly(MTAC) was optimized as follows: discharge time 60 s and discharge power 60 W.
