Abstract
Improvements in the processes for the manufacture of styrene polymers, characterized in that the styrene monomer is introduced into a prepolymerization tank where a catalyst product, a molecular weight regulating product, an internal lubricant and stearic acid are added slowly. , raising the temperature to 110-120º C for one hour, after which it is maintained for 7-10 hours at a temperature of not less than 90º C, these circumstances being prolonged until the refractive index or viscosity give a conversion of the order of 35%, at which time the material is taken to a polymerization press where, at a temperature of the order of 160-190º C, the complete reaction is reached.
