| Abstract: | The potassium polyvinylsulfate (PVSK) was synthesized by using different types of polyvinylalcohol (PVA), the ester value of the PVSK was determined by the method of BaCl_2 titration. The effect of polymerization degree and hydrolysis degree of PVA on the ester value of PVSK was discussed. The best selection of PVA for high performance PVSK was decided. The synthesized high ester value PVSK was characterized and compared with high ester value PVSK sample from Japanese company. |
