Influence of different factor levels on the grafting rate: a) the influence of temperature on the grafting rate (12h, 4% crosslinker), b) the influence of time on the grafting rate (EGDE: 80°C, 4% crosslinker. TTMA:50°C, 4% crosslinker.), and c) the influence of the amount of crosslinker (EGDE: 80°C, 16h. TTMA:50°C, 12h.)
