“…One of the compounds they obtained was poly(ethylene)- g -PCTFE which has better hydrophobic properties and better biocompatibility. This technique was also applied to synthetic fibers. , In a related approach, various authors , demonstrated that the peroxy radicals generated on PCTFE by irradiation are persistent and can survive for more than 6 years. Evidence of the slow decay resulted from the successful graft polymerization of styrene initiated by the remaining peroxy radicals onto preirradiated films after various storage periods.…”
