METHOD FOR INCREASING SOLID STATE POLYMERIZATION RATE

1. A process for polymerizing low molecular weight polyesterprepolymers in the solid state which comprises: (a) contacting the particles with a heat transfer medium to heat the particles to a temperature in the range of from about 205 degree C to 240 degree C in less than 10 minutes with the result...
