## Abstract Improved methods for measuring weightโ and numberโaverage molecular weight of polymers soluble only at elevated temperatures are applied to selcted samples of polyethylene. For two samples of essentially linear polyethylene, numberโaverage molecular weights by cryoscopy are 11,500 and 1
## Abstract When a swollen elastomer is in equilibrium with a solution, the stress at constant length is a function of the chemical potential of the solvent, and thus of the concentration and numberโaverage molecular weight of the solute in the solution. This is used to compare the molecular weight
## Abstract In studies of various polymers in the solid state by pulsed and wideโline NMR, a relationship between the spinโlattice relaxation time and the fraction of mobile protons in the polymer sample was observed. This effect has been used to determine the degree of polymerization of a series o
