## Abstract The connection between intrinsic viscosity and number‐average and weight‐average molecular weight has been revealed by calculations from distribution curves. Log‐normal distributions, and moderate variations thereon, were chosen as typical for polystyrene and other thermoplastics. Intri

## Abstract The weight‐average molecular weight is estimated by an extrapolation technique based on a linear relation between the viscosity‐average molecular weight __M__~__v__~ and a Mark–Houwink–Sakurada constant. This method may also be used to assess the unperturbed dimensions of polymers. If t

## Abstract Polyurethane films were prepared by solution casting using a three‐component system consisting of polymeric MDI, a propylene oxide‐based polyether triol and kraft lignin fractions of different molecular weights. The polyether triol was used as soft segment. The composition of the polyur
