What is A Light Scattering Study of Alfin Polybutadiene about?
## Abstract The weight average molecular weights, __M__~__u__~, of some unfractionated Alfin polybutadienes ranged from 5 to 20 million. The ratio of the mean‐square radius of a linear polybutadiene molecule to its molecular weight in a thermodynamically neutral solvent is estimated to be __R__^2^/__M__ = 2.2 (±0.3) × 10^−17^ cm.^2^g.^−1^ mole. The relationship [η] = 0.125 __M__~__v__~^0.77^ between intrinsic viscosity and molecular weight is estimated for linear polybutadiene in cyclohexane at 25°. The average value of Φ′, the parameter in the Flory‐Fox theory of intrinsic viscosity, is found to be 3.6 × 10^24^ mole^−1^ (or Φ = 2.5 × 10^23^ mole^−1^) for linear molecules and appears to increase with branching. Branching is found to decrease with increasing conversion for this polymer. Values of the osmotic second virial coefficient, __A__~2~, are discussed in connection with theoretical predictions. Various corrections to measured quantities required because of polydispersity in polymer samples are presented.
