n-heptane and mixture of butanone and n-heptane (2:1
volume) at 30℃were determined and were found as follows:MW was measured by light scattering method. The mixed solvent at the given temperature was found to be aθ solvent. The unperturbed dimension of cis-1
4-polybutadiene was estimated with KS
SF
and IP equations to be 0.0901nm
0.0928 nm and 0.091 5nm respectively and the value obtained at θ condition is 0.0896nm.
