| Abstract: | It was polymerized in emulsion by the redox initiator which was ammonium persulfate/sodium bisulfate/formaldehyde sodium bisulfateas.The effects for PVAc at intermediate temperature by the amount of initiator,the amount of emulsifying agent,polymerization temperature were discussed.When emulsifying agent and initiator were 0.15% and 0.6%,respectively,the temperature could decrease to 45 ℃,the milky emulsion had a property that viscosity was 5.8 Pa·s,and solid scontent was 50%. |
