Versuchsvorschrift

A copolymer was synthesized as in Polymer Synthesis Example 1 except that 3-[tris(trimethylsilyloxy)silyl]propyl methacrylate and t-butyl methacrylate were used instead of 1,4,4-trimethyl-4-silacyclohexyl methacrylate. The polymer was confirmed by the light scattering method to have a weight average molecular weight of 13,000 g/mol and by the GPC elution curve to have a dispersity (Mw/Mn) of 1.78. By 1H-NMR analysis, the copolymer was found to contain the components in a ratio of approximately 2:5:3.
