Abstract:
Polymers, particularly those used in pressure-sensitive adhesives, are prepared from a mixture of structural isomers of a secondary alkyl (meth)acrylate monomer. The adhesives are characterized by exhibiting an overall balance of adhesive and cohesive characteristics and exceptional adhesion to low surface energy substrates.
Abstract:
Compounds are described that have both an aziridinyl group as well as a polymeric group. Methods of making these compounds are also described. The aziridinyl group of the compound can be reacted with an acidic group on a second compound resulting in the opening of the aziridinyl ring and the attachment of the polymeric group to the second compound.
Abstract:
A pre-adhesive composition is described comprising an acid- and epoxy-functional (meth)acryloyl copolymer, which when crosslinked using an ionic photoacid generator (PAG) provides a pressure-sensitive adhesive and pressure-sensitive adhesive articles having desirable properties.
Abstract:
Pressure-sensitive adhesive compositions and articles containing the pressure-sensitive adhesives are provided. The pressure-sensitive adhesives contain an (meth)acrylic-based elastomeric material prepared from (2-isopropyl-5-methyl)hexyl (meth)acrylate.
Abstract:
Oxazolinyl-containing compounds having a single oxazolinyl group plus a first polymeric group are described. Grafted compounds are also described that are the product of a reaction of an oxazolinyl-containing compound with a second compound that has one or more acidic groups to form a grafted compound. In some embodiments, the second compound is a polymeric material having at least one acidic group and the reaction product is a grafted copolymer. Blended compositions of the grafted copolymer with a polyamide are also described.

Abstract:
Compositions are described that are blends of a grafted copolymer and a polyamide. Methods of making the blended compositions are also described. The grafted copolymers are the reaction product of (1) a first compound having both an aziridinyl group and a polymeric group with (2) a second polymeric material having an acidic group. Blending the grafted copolymer with the polyamide can be used, for example, to increase the cohesive strength of the grafted copolymer.
