Title:
METHOD FOR PRODUCING COPOLYMER
Document Type and Number:
Japanese Patent JP2021109887
Kind Code:
A
Abstract:
To provide a method for producing a copolymer suitably used for an adhesive composition having improved thermal creep resistance and hygrothermal creep resistance.SOLUTION: The present disclosure provides a method for producing a copolymer having a vinyl ester unit 100 pts.mass, and an ethylene unit 5-45 pts.mass and a polyfunctional monomer unit 0.01-0.2 pt.mass. 0-30% of the total amount of charged polyfunctional monomers is charged in a polymerization can at the start of polymerization, and the remaining polyfunctional monomers are post-added to the polymerization can between 2 hours and 6 hours since the start of polymerization.SELECTED DRAWING: None
