Proposes a two-stage experimental approach that combines preparative chemistry and polymer characterization. Describes the simple organic synthesis of a plasticizer, the dioctylphthalate, and its direct use in the preparation of a styrene/divinylbenzene network copolymer. Discusses how to evaluate the physical properties of the resulting plastic.…

Describes six laboratory procedures for preparing polymers which have been used in a course for undergraduate industrial arts students, who have a concentration in plastics technology but have not taken more than one year of college chemistry. (BT)
