The paper is concerned with the evaluation of ultrahigh molecular weight poly(methyl methacrylate) dimensions over a wide concentration range in different solvents, by use of a model proposed by Qian and Rudin. The model allows the estimation of the unperturbed dimensions, and the obtained values ar
The behaviour of ultra-high molecular weight poly(butyl methacrylate) (/~w = 9.59 Γ 106-24.50 Γ 106) in dilute solution in methyl ethyl ketone, benzene, dioxane, and cyclohexanone, at 25c'C. has been investigated by viscometry. Mark Houwink relations have been established, and the unperturbed dimens
