Abstract
The present disclosure provides an oil-resistant adhesive comprising a crosslinked copolymer of (meth)acrylic ester monomers, methyl (meth)acrylate monomers, vinyl ester monomers, and a functional monomer selected from one of (meth)acrylic acid, a (meth)acrylamide or a hydroxyalkyl (meth)acrylate monomers.
Claims17
A crosslinked adhesive copolymer composition, the copolymer comprising:
- a) 30 to 60 parts of a (meth)acrylic ester monomer, wherein the (meth)acrylic ester monomer is a monomeric (meth)acrylic ester of a non-tertiary alcohol, which alcohol contains from 2 to 14 carbon atoms,
- b) 40 to 60 parts of methyl acrylate monomer,
- c) 2 to 15 parts of vinyl ester monomers, and
- d) 0.1 to 5 parts of an acid functional monomer,
- where the sum of a) to d) is 100 parts by weight.
