In 1925 Naugatuck Chemical Company built a commercial styrene/polystyrene plant, but it only operated for a short time. From this point I. G. Farben Industrie in Germany and Dow Chemical in the United States pursued commercialization of styrene and polystyrene. Both companies independently developed along similar routes. 

The high-impact PS, HIPS, has been known since 1911 [Matthews, 1911, 1913]. In the USA, Ostromislensky [1924, 1926-28] patented copolymerization of styrene with rubber, balata or other elastic and plastic gum . Production of HIPS, Victron , by the Naugatuck Chemical started in 1925, but soon it was discontinued.

In 1925, the Naugatuck Chemical Co. (Uniroyal) in the USA initiated production of polystyrene (PS) in 1930, Dow Chemical Co. and IG Farbenindustrie in Lud-wigshafen started production. Styrene gained more importance during World War II, particularly in the production of rubber-like copolymers with butadiene.

On the other end of the composition spectrum is the impact modification of PS by incorporation of well-dispersed mbber particles. In the early 1920 s several patents on polymerization of acrylics or vinyls, e.g., styrene and its derivatives, were granted to Ivan I. Ostromislensky, and assigned to Naugatuck Chemical Co. In 1925 he wrote the first patent on high impact polystyrene, HIPS, specifying... 

Paracril RF, said to have been produced through a free radical mechanism, was distributed for a few years by the Naugatuck Chemical Co. This material was a liquid of viscosity 50 poise at 25°C and a = 3500. 

The story of these systems begins as long ago as 1925. Ostromislensky [70] of Naugatuck Chemical filed a patent application for the polymerization of a natural rubber solution in styrene. This produced a tough white thermoplastic in the place of a brittle, glassy, transparent... 

The Naugatuck Chemical Company, Connecticut, a subsidiary of U.S. Rubber, was the first company to manufacture styrene. The process, however, was based on the hydrodechlorination of ethylbenzene and the product was not sufficiently pure for use in polymer applications. The company had received assistance from Igor Ostromisslenski, a well-known Russian emigrant, who held several patents in the field." ...
