✦ Synopsis

Natural rubber in latex form was reacted with performic acid generated in situ. Due to high acidity of formic acid, the oxiranes formed were readily ring-opened to give hydroxyformate and glycol. In most cases, the latex coagulated within 2 hr of reaction and further reaction of the rubber coagulum resulted predominantly in the formation of tetrahydrofuran ring. Cross-linking is believed to occur via the formation of ether linkages. An i.r. technique for the analysis of the insoluble rubber is described. Quantitative analysis of the reaction products was made possible by using the methyl deformation band at 1380 cm-t as internal standard.
