ABSTRACT:
The process comprises (co)polymerization of the starting monomers in the presence of radical initiators at monomer concentrations of from about 40 to about 100% by mass at the temperature of decomposition of the initiator employed until the appearance of the gel-effect and formation of a low-molecular prepolymer. The prepolymer is cooled to the glass-transition temperature with a degree of conversion thereof of about 50 to 90%. The resulting high-molecular prepolymer is granulated and treated with a heating agent in a pneumatic conveyor, cyclone, fluidized bed and filtering bed.
