Interpenetrating Polymerization of Styrene in Polypropylene and Poly(Ethylene Terephthalate) Using Microwave Irradiation
Main Article Content
Abstract
Abstract
The preparation of interpenetrating polymer is one of the most efficient methods for modifying or improving polymer properties. In this work, interpenetrating polymerization of styrene in polypropylene (PP) and poly(ethylene terephthalate) (PET) using microwave irradiation was investigated. The immobilization percentage of polystyrene as a function of the initiator/monomer ratio, reaction time, and microwave power was studied. Immobilization percentages up to 30 and 16 % in PP and PET, respectively, were achieved in less than 20 min of microwave time. The interpenetrating polymers showed superior chemical stability in both acidic and basic media for several days over their pristine counterparts while their thermal and mechanical properties were comparable, indicating that the new materials reported in this research can be used as substitutes for various applications. Furthermore, the microwave method developed in this work provides efficient, versatile, and simple method for the preparation of chemically stable interpenetrating polymers, and can be used to modify the structure and properties of polymeric substrates.
Keywords: interpenetrating polymer; poly(ethylene terephthalate); polypropylene; polystyrene; microwave irradiation
