The molecular behavior responsible for the observed tensile strength properties of unfilled rubbers has been studied in a recent paper from this laboratory. In the present paper we intend to extend that work to the case of rubbers which are filled wi

The measured viscosity of bulk polymers and their solutions varies with the magnitude of the applied shearing stress. In this paper we show that this is a natural consequence of the fact that the molecules are caused to rotate by the shearing action.

A method for determining molecular weight distributions is presented, based upon the partition of polymer molecules between gel and sol in a partly crosslinked system. It is assumed that the polymer sample consists of a series of molecular weight spe

Expressions are derived from free volume considerations which predict the concentration dependence of viscosity and glass temperature for polymer-diluent systems. Experimental data for several systems were examined and general agreement with theory w

Model branched polymers have been prepared by the reaction of relatively monodisperse polystyryl lithium with silicon tetrachloride. The branched molecules have been carefully characterized by light scattering and osmotic pressure measurements. A stu

A new molecular theory of tensile strength has been formulated for amorphous gum vulcanizates at temperatures well above the glass temperature and found to be in agreement with recent experimental data. It is shown that the stress on the rubber at br

A previously reported theory for the Mullins softening effect has been used to interpret various new data for the behavior of filled SBR rubber under tensile load. The strength of the filler–rubber bond, the filler surface area per polymer molecule

The viscosity of molten polymers and their concentrated solutions is investigated theoretically. Both linear and branched polymers are considered. Two methods are used, one being merely an extension of a previous computation for linear polymers. Esse
