AQUEOUS ADHESIVE COMPOSITION Russian patent published in 2018 - IPC C09J133/08 C09J133/06 

FIELD: technological processes.

SUBSTANCE: aqueous adhesive composition is provided comprising a polymer comprising (a) polymerized units of one or more alkyl(meth)acrylate monomers, (b) polymerized units of acrylic acid or methacrylic acid or a mixture of these compounds, (c) polymerized units of one or more dialkyl dicots of itaconic acid and (d) polymerized units of one or more other monomers. Invention relates to an adhesive composition for a wide variety of purposes. Aqueous adhesive composition comprising a polymer comprising: (a) polymerized units of one or more alkyl(meth)acrylate monomers in an amount of 80 % to 99 % by weight relative to the dry weight of said polymer, (b) polymerized units of acrylic acid or methacrylic acid, or a mixture of said compounds in an amount of 0.1 % to 10 % by weight relative to the dry weight of said polymer, (c) polymerized units of one or more dialkyl diesters of itaconic acid in an amount of 2 % to 15 % by weight relative to the dry weight of said polymer and (d) polymerized units of one or more other monomers in an amount of 0 % to 20 % by weight relative to the dry weight of said polymer.

EFFECT: adhesive composition is proposed that maintains an acceptable level of shear characteristics and has an increased tack value.
