Abstract
A process is provided for preparing a vulcanized carbon black-reinforced chloro- or bromobutyl rubber film comprising admixing a polyfunctional amine vulcanization system with a carbon black-reinforced chloro- or bromobutyl rubber latex containing one or more selected emulsifiers, forming a film from the resulting mixture, drying said film and heating the dried film to provide the vulcanized film. The process may be used in the manufacture of coatings, dipped goods and chemical resistant impermeable treated fabrics.
