where W1 and W2 are weight of mixture before and after drying respectively.
11.2.6 GRAFTING VERIFICATION
Physicochemical characteristics of synthesized PAM, gelatin and PAM-g-gelatin co-
polymers were studied using FTIR Spectrophotometer (Shimadzu FTIR-8400 S, Ja-
pan) and TGA (Shimadzu TGA -50, Japan). Morphological characteristics were fol-
lowed using analytical SEM (Joel JSM 6360LA, Japan).
11.3 DISCUSSION AND RESULTS
11.3.1 GRAFTING PROCESS
EFFECT OF POLYMER (GELATIN) CONCENTRATION
Table 1 shows the effect of variation of gelatin in the range of (2–10%) on the graft-
ing percent, grafting efficiency ...
