Copolymerization of 2-acrylamido-2-methylpropane sulfonic acid (AMPS, monomer 1) with 2-hydropropyl methacrylate (HPM, monomer 2) was conducted in ethylene glycol/water (1 : 1 in weight) at 70ะC. The reactivity ratios estimated from the copolymer composition at low conversion are r 1 ร 2.31 { 0.25 a

## Abstract For solutions of polystyrene (PS) samples of different relative molecular mass (molecular weight) __M__ and intrinsic viscosities [__n__] have been measured at 298,15 K in pure toluene (T) and toluene/methanol (MeOH) mixtures. Upon mixing toluene (good solvent (1)) and methanol (nonsolv
Air,watt--Intrinsic viscosity vs. composition curves of block copolymers of polyisoprene and polystyrene in a mixed solvent (cyclohexane q-n-heptane) show a transition at a critical composition (Yc) provided the temperature of the system is above a conformational transition temperature (T)) found pr
