Research of Physico-Mechanical Properties of Modified Polystyrenes

29372

Polystyrene is one of the most widely used synthetic polymer in daily life. In this study, the chemical modification of polystyrenes which have different molecular weight, with maleic anhydride and acetic anhydride in the presence of catalyst (BF3∙O(C2H5)2 ) and in the optimum conditions which have been found in previous studies, has been done and some polyfunctional groups (CH3CO- and -CH2-CH=CH-COOH) containing polystyrenes have been manufactured. Various physico-mechanical properties as tensile strengths, softening temperatures and hardness determination of modified polystyrenes have been researched. Finally, modified polystyrenes have been compared depending on functional groups.
