A Uniform Design for Preparation of Poly(chitosan-co-acrylonitrile)
Abstract:
The uniform design and statistical analysis system(SAS) have been employed to study the reaction conditions of graft polymerization of acrylonitrile(AN) onto chitosan using K2S2O8-NaHSO3 as initiators. The optimum reaction conditions as follows:K(chitosan)=3.35%, K(HAc)=2%, n(AN)/n (chitosan)=7, n(chitosan)/n(K2S2O8)=6, n(NaHSO3)/n(K2S2O8)=0.538, reaction time 3.5 h, temperature 40℃, grafting efficiency being 92.24%. The results showed that the uniform design, as compared with the orthogonal factorization method, has the advantages of timesaving and easier analyse of the influence factors.
