Abstract

This report deals with sulfur of thioketon type and that of crosslinked type as well as with chlorine.<br>(1) It was experimentally recognized that as the solution for vulcanization becomes more concentrated, so does sulfur of either type increase in quantity, on condition that vulcanization is continued only for a short period of time. When rubber is vulcanized for a long time, however, sulfur does not necessarily increases in accordance with high-concentration in the solution.<br>(2) Based on the quantitative experiment of aceton-extracts, free sulfur, thioketon-type sulfur, crosslinked-type sulfur, chlorine, etc., the reaction mechanism of natural rubber with S2Cl2 in the solution was considered as the following principal reaction:_??_
