Embodiment 1
[0013] A 45% solids copolymer adhesive solution with 70 parts vinyl acetate, 15 parts acrylic acid, and 15 parts methyl methacrylate was prepared.
[0014] In the reactor with temperature agent, reflux condenser, and stirring, first add 70 parts of vinyl acetate, 15 parts of acrylic acid, 15 parts of methyl methacrylate and 0.005 parts of ammonium persulfate, and heat the reactor to about 74 ° C , to react, when the conversion rate of the monomer reaches 30%, add 60 parts of methanol and 0.3 part of ammonium persulfate, and react under reflux for 12 hours. After the reaction was completed, the temperature was lowered to 30° C., and 62 parts of ethyl acetate were added. The reaction product was a 45% terpolymer composition solution adhesive.
Embodiment 2
[0016] A copolymer solution adhesive with 80 parts of vinyl acetate, 10 parts of acrylic acid, and 10 parts of butyl acrylate was prepared with a solid content of 40%.
[0017] In a reactor, first add 80 parts of vinyl acetate, 10 parts of acrylic acid, 10 parts of butyl acrylate, and 0.03 parts of ammonium persulfate, and then heat the reactor to about 74 ° C for insulation reaction. When the monomer conversion rate reaches 50%, add 150 parts of ethanol and 0.2 part of ammonium persulfate, and react under reflux for 10 hours.
[0018] The reaction product is a terpolymer composition solution adhesive with a solid content of 40%.
Embodiment 3
[0020] A copolymer solution adhesive having a solid content of 35% and having 50 parts of vinyl acetate, 10 parts of acrylic acid, 30 parts of butyl acrylate and 10 parts of methyl methacrylate was prepared.
[0021] Add a mixture of 50 parts of vinyl acetate, 10 parts of acrylic acid, 30 parts of butyl acrylate, and 10 parts of methyl methacrylate into the reactor, and at the same time add 0.02 parts of azobisisobutyrocyanide to heat the reactor Carry out heat preservation reaction at about 78°C. When the monomer conversion reaches 50%, add 60 parts of ethanol and 0.2 parts of azobisisobutyronitrile, react under reflux for 10 hours, cool down to 30°C, and then add 226 parts of ethanol. The reaction product was a solution adhesive of a tetrapolymeric composition with a solid content of 35%.
