摘要

Isotactic polypropylene fiber (IPP) was graft-copolymerized using 2-vinyl pyridine (2-VP) and styrene (sty) as teh monomers by teh mutual irradiation method in air. The percentage of grafting was determined as a function of various reaction parameters and it was found that the maximum grafting of 2-VP(114%) and sty (76%) was obtained at an optimum dose of 1.08×10~4 and 0.64×10~4 Gy using 1.8×10~(-2) mol of 2-VP and 4.3×10~(-2) mol of sty, respectively. The graft copolymers were characterized by differential scanning calorimetric analysis and isolation of the grafted chains from the grafted iPP samples.
