METHOD FOR THE PREPARATION OF (METH)ACRYLIC POLYMERS

摘要

Method for the preparation of a (meth)acrylic polymer, comprising at least one sequence S predominantly comprising at least one (meth)acrylic monomer M, by means of a titanium complex of formula (I) activated by at least one cocatalyst: characterized in that the sequence S is obtained at a polymerization temperature of >40° C, advantageously >60°C, preferably >100°C. The invention also relates to the method for fabricating a PMMA plate using the casting method consisting of: introduction of a composition to be polymerized comprising the MAM and possibly at least one comonomer which can be copolymerized with the MAM, as well as of the activated titanium complex into a casting mold, followed by placing the casting mold in a heat insulating device; and once the polymerization has been completed, the PMMA plate is removed from the casting mold.
