| 摘要 |
This invention relates to the polymerization of a monomer capable of forming a precipitate of polymerized particles which comprises reacting in the liquid phase said monomer in the presence of a high temperature, free radical initiator at a temperature within a critical range of between about 110 DEG and 150 DEG C. to produce a particulate polymeric product having a glass transition temperature. (Tg) in excess of the temperature at which polymerization is effected and having a residual monomer content less than 1,000 ppm.
