## Abstract The molecular weight dependence of the Lower Critical Solution Temperature in polymer solutions has been derived using the Prigogine smoothed potential cell model. Satisfactory agreement is obtained with experimental results for a number of systems. It is found that the new structural t
Cloud point curves (CPC) have been measured for 1-4 cis polybutadiene (My = 40,000-830,000) in n-hexane, 2-methyl-hexane, 2.2,3 trimethylbutane and 2,2,4 trimethylpentane. These four systems show upper and lower critical solubility temperatures which approach one another as the molecular weight incr
