✦ Synopsis

Polyblends which undergo two distinct modulus transitions between glassy and rubbery behavior have been made from sulfur-vulcanized diene rubbers. In these blends butyl rubber or polyisobutylene is used to form the rubbery phaee of a mixture in which an appropriate diene polymer is converted to resinous hard rubber by sulfur vulcanization. Data are given to illustrate the modification of modulus produced in polyblends bsaed on hard rubber mixtures and to show the importance of marginal compatibility in determinimg the properties of the product.
