ABSTRACT:
A continuous process for producing plate-like polymer articles which comprises subjecting a liquid polymerizable composition comprising a syrup of methyl methacrylate and a specified amount of a polymerization initiator of the formula: ##STR1## (in which R is a C.sub.4 -C.sub.10 alkyl or alkoxyalkyl group), to a casting polymerization at a specified temperature. By this process, plate-like polymer articles having a high quality can be obtained in a very short polymerization time.
