摘要：
Anionic polymerization of higher alkyl methacrylates was investigated. Polymerization was performed in a jacketed glass-resin kettle under a nitrogen atmosphere at -30 °C. Gel permeation chromatography (GPC) and weighing of the dried polymer after precipitation in a nonsolvent, were used to determine monomer conversion ratios. Fast addition of the monomers produced lower molecular weight distribution (MWD) polymers than slow addition processes.
