【Abstract】 The effects of various factors on the water-solubility and viscosity of acrylic resins were investigated. The water-solubility of the resins mainly depends on the content of AA in the resins and the extent of neutralizing —COOH . The viscosity of the aqueous solution of the resin mainly depends on dosages and types of molecular weight modifiers and cosolvents. The ‘viscosity-peak phenomenon’ mainly depends on the content of AA,the extent of neutralizing —COOH and types of cosolvents.更多还原
