Abstract
Pressure-sensitive adhesives are prepared from (meth)acrylate esters of 2-alkyl alkanols. The adhesives are characterized by exhibiting an overall balance of adhesive and cohesive characteristics and exceptional adhesion to low surface energy substrates.
Claims17
A pressure-sensitive adhesive composition comprising (co)polymers of:
- a) 51 to 99 parts by weight of an (meth)acrylic acid ester monomers of 2-alkyl alkanols wherein the molar carbon number average of said 2-alkyl alkanols is 12 to 32;
- b) 1 to 49 parts by weight of (meth)acrylate esters of C1-12 alkanols;
- c) 0 to 15 parts by weight of an acid functional ethylenically unsaturated monomer;
- d) 0 to 10 parts by weight of a non-acid functional, ethylenically unsaturated polar monomer;
- e) 0 to 5 parts by weight of a vinyl monomer;
- and
- f) 0 to 5 parts by weight of a multifunctional (meth)acrylate;
- based on 100 parts by weight total monomer, and
- wherein the molar carbon number average of the alkanols of the a) and b) (meth)acrylic acid esters is 12 to 32.
