Summary

Critical solution point and chain dimension were measured for branched polystyrene(BPS) in solution as a function of molecular weight(M) and compared with those for linear polystyrene(LPS). The critical concentration φc of BPS was quite different from that of LPS at a fixed M, but the same at a fixed overlap-concentration φ*, i.e., plots of φc vs. φ* fall on a single straight line for both BPS and LPS (gfc ∝ φ*). Reduced critical temperature τc defined by gtc=(θ−Tc)/θ [Tc: critical temperature, θ: the θ-temperature] was related to φc as τc ∝ φc∼2 for BPS, whereas τc ∝ φc for LPS.
