The first modification of rubber by incorporation of polystyrene (PS) is credited to Francis Edward Matthews, who during the years 1911-1913 (Figure10.1) received several international patents for the manufacture of lacquers and ‘articles that are normally made of hard rubber, celluloid, vulcanite, ebonite, glass, wood and similar materials’. He further specified that ‘expecting finer dispersion and better control’, 100 parts of rubber were mixed with 50 parts of styrene, then the polymerization was initiated to obtain either a thermoplastic blend or a vulcanizable rubber (Matthews, 1911, 1913).
