DOCUMENT TYPE: Journal CA Section: 37 (Plastics Manufacture and Processing) P-Styrenesulfonate derivs. having cycloaliph. epoxide in a mol., were synthesized. Oligomerization of the monomers and co-polymn. of the novel monomers with tert-Bu methacrylate were carried out. When the polymer films contg. a photoacid generator (PAG) were irradiated, they became insol. in solvents. The insol. films became sol. in water on baking at 120-200°. The insolubilization and redissoln. profiles were strongly affected by the structure of the monomer, irradn. and baking conditions, and a type of PAG used.Some commonly used reagents like 1679-51-2 is used in this experiment. The reaction mechanism was studied by TGA anal. and FT-IR spectroscopy. .
