tert-Butanol → Styrene acrylic acid copolymer

Participants

Reaction Conditions

Reaction Steps

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.
