Procedure:
Air in a 20 ml Schlenk tube was replaced by Ar gas and 1.02 g (7 mmol) of m-ethynylbenzoic acid and 5 g (42 mmol) of thionyl chloride were added to the tube and the mixture was stirred at 50° C. for 2 hours and then excess thionyl chloride was removed by distillation under reduced pressure to obtain m-ethynylbenzoyl chloride. To the m-ethynylbenzoyl chloride obtained was added 7 ml of THF and the resultant mixture was ice-cooled. Then, 971 mg (7.35 mmol) of sodium benzenethiol was added to the mixture and the resultant mixture was stirred at room temperature for 2 hours. After completion of the stirring, THF was removed by distillation under reduced pressure and 35 ml of water was added to the resultant residue. The mixture was extracted with 35 ml of ethyl acetate, the extract was dried over magnesium sulfate and the solvent was removed by distillation under reduced pressure using an evaporator. The resultant crude reaction product was purified by column chromatography (Hexane/AcOEt=20/1) using silica gel to obtain 0.51 g of S-phenyl 3-ethynyl-thiobenzoate which is a desired product as yellow solid.

Procedure:
Two additional styrene/acrylic acid copolymers were prepared by solution polymerization (in tert-butanol at 30% monomer concentration). Benzoyl peroxide (2.0 mmoles/mole monomers) was added to the reaction mixture which was then purged with nitrogen for 10-15 min and heated to 80° C. for 16-20 hours. In the early stages of the reaction, an ice bath was used to moderate the exotherm. The resulting polymer was isolated by precipitating in water and drying in a vacuum over (60° C./1 torr). After drying, monomer conversion to polymer was measured, and the inherent viscosity (25° C. using a 0.2 wt % solution in tetrahydrofuran), and the composition (using 13C NMR of the polymer products) were determined. The characteristics of these polymers is noted in Table 5.
