ABSTRACT
I. INTRODUCTION In 1972 Phillips Petroleum Company started up a new plant to produce a new family of styrene plastics known as K-Resin BDS polymer. The resins are clear and tough and their moderate pricing places them between the low-cost resins such as polystyrene, polyethylene, and polypropylene, which are either clear or tough, but not both, and high-priced resins such as cellulosics, clear ABS, and polycarbonate, which are both clear and tough. The exceptional clarity and impact resistance make them desirable replacements for conventional polystyrene and other clear resins in many applications. Applications thus far realized are in toys, housewares storage units, lids, medical packaging and devices, films, and a wide variety of packaging uses including blister packs, injection-molded tubs, bottles, and boxes with integral hinges [1].
