Abstract

The viscometric behaviour of poly(p-tert-butylphenyl methacrylate) in a binary mixture (acetone/cyclohexane) has been studied. This mixture presents a type of partial co-solvency (synergism) for this polymer: cyclohexane is a θ-solvent at 25° and acetone is very poor. The conformational parameter seems unaffected by the nature of this binary solvent mixture. The results are discussed in relation to the behaviour of the poly(p-tert-butylphenyl methacrylate) in some pure solvents, viz. acetone, cyclohexane and tetrahydrofuran. This viscometric behaviour is compared with that of polystyrene in the same mixture.
