Abstract
A bulk polymerization reactor takes the form of a vertical, cylindrical vat of a jacket construction defining a reaction chamber which a rotary drive shaft having an off-center longitudinal section with perforated discs and shearing blades extends vertically through. Successful preclusion of abnormal stagnation of the liquid phase in the reaction chamber during polymerization avoids undesirable coloring in the product while assuring stable polymerization and high yield.
