Starch-acrylamide graft copolymer-aqueous solution polymerization (2)

(5) Monomer dosage

The monomer dosage is in the range of 2.

(6) Reaction medium

Starch and acrylamide react in different media, and the grafting effect is different.

Figure 3-8 The effect of reaction time on the grafting effect.

Figure 3-9 The effect of monomer dosage on grafting effect

Table 3-34 The influence of reaction medium on the grafting effect

In a word, in the preparation process of starch-acrylamide graft copolymer, the factors that affect the grafting effect are comprehensively studied, and the best conditions for preparing starch-PAM copolymer are: the amount of starch is 10.

Many domestic scientific researchers have also done a lot of research work in the research of starch acrylamide graft copolymers.
