Abstract

The invention relates to sulfur-containing polymethacrylates P produced by radical polymerization of monomers of formula I: ##STR1## where Y represents a C.sub.2-12 alkyl group, a C.sub.2-12 branched alkyl group, a C.sub.3-12 cyclic alkyl group, a C.sub.6-14 aryl group, or a C.sub.7-26 alkaryl group, wherein the carbon chains of Y may be interrupted by one or more ether or thioether groups; and PA1 R represents hydrogen or methyl; and PA1 wherewith the polymer P contains, in addition to units of monomer(s) of formula I, units of at least one monomer of formula II: ##STR2## where R and Y have the same meanings as above; and n is an integer in the range 1 to 6.
