Krishna Venkataswamy, Craig Allen Chmielewski: Staged condensation, dynamic vulcanization process for making a substantially unplasticized plastic/rubber blend. Advanced Elastomer Systems, Alfred D Lobo, William A Skinner, December 21, 1999: US06005052 (4 worldwide citation)

This invention describes a staged process in which successive dynamic vulcanizations of plural curable rubber blend components are based on condensation reactions of a functional group (reactive site) carried by each curable rubber. The process is carried out in three stages during each of which gas ...
