An adiabatic copper calorimeter was used to determine the heats of vulcanization of pale crepe natural rubber with sulfur for mixtures varying in composition from 0 to 32 per cent added sulfur. The side reaction that produces hydrogen sulfide was avo

Crystals may be formed in natural rubber under varied experimental conditions. Different combinations of stretching and cooling have been used to induce crystallization in unvulcanized and in vulcanized rubber. The appearance and disappearance of cry

It is, indeed, a very great honor to have been chosen as the Charles Goodyear Medalist for 1967, and I very much appreciate the opportunity of coming here to tell you about some of the research work in the field of rubber with which I have been assoc

Rubbers from different sources vary considerably in rubber hydrocarbon content, from 70 per cent or less for some of the wild varieties to about 95 per cent for a good grade of plantation rubber. The quality of a rubber is measured to a great extent

The purpose of this paper is to show how thermodynamic data on rubber and related substances can be employed in studying and predicting their reactions. The method will be illustrated by the results of recent studies on rubber and iso-prene made at t

The formation of crystals at room temperature by stretching rubber, vulcanized or unvulcanized, has been the subject of considerable study. The crystallization of unstretched rubber at low temperatures is also well known, but with a single exception
