Process for the Preparation of

Mitsubishi Gas Chemical Company,
Inc. of Japan has patented a process for
the preparation of a powder coating composition,
comprised of: copolymerizing
five-90% by weight of at least one compound
selected from the group consisting
of glycidyl group-containing unsaturated
compounds and methylglycidyl groupcontaining
unsaturated compounds with
95-10% by weight of and ethylenically
unsaturated monomer in methanol to
obtain a resin solution; feeding the resin
solution to an extruder having a die and
a plurality of vent ports; while removing
volatile matters existing in the resin solution
in the extruder from the extruder
through the die to obtain extrudates and
pulverizing the extrudates.
