| Abstract: | Water-soluble polyvinyl butyral(WPVB) was prepared by the water-borne grafting modification of polyvinyl butyral(PVB) with phthalic anhydride.IR spectra and H NMR were used to characterize the WPVB,and the factors that influenced the reactions were also studied with the following optimal reactions conditions being found:reaction temperature 60℃,reaction time 6 h,w(TBAB) = 0.6%.The aqueous dispersion of WPVB was prepared,and the performance of the curing coating was researched.The following conclusions were obtained:comparing with PVB,the glass transition temperature decreased 11.6℃,the total weight loss rate decreased 1.59%,the hardness changed from 5 H to 7 H,and the adhesion level changed from 1 to 0 for WPVB. |
