Abstract:
A pre-adhesive composition is described comprising an acid- and epoxy-functional (meth)acryloyl copolymer, which when crosslinked with or without 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 an alkyl (meth)acrylate having an alkyl groups that is branched and that contains at least 14 carbon atoms.
Abstract:
The disclosure describes a curable composition comprising a) a solute (meth) acryloyl oligomer having a plurality of pendent, ethylenically unsaturated, free-radically polymerizable functional groups and nucleophilic, hydrophilic groups, a Mw of 5 k to 30 k. a Tg
Abstract:
This disclosure relates to viscoelastic damping materials and constructions which may demonstrate low temperature performance and adhesion and which may be used in making vibration damping composites. Viscoelastic damping materials and constructions may include polymers or copolymers of monomers according to formula (I): CH 2═CHR1—COOR2 wherein R1 is H, CH3 or CH2CH3 and R2 is a branched alkyl group containing 12 to 32 carbon atoms.
Abstract:
Disclosed are copolymers which comprise: a) an isobutylene copolymer having grafted polymer groups, b) optionally a tackifier, and c) optionally a non-functionalized poly(isobutylene) polymer. The compositions are useful in adhesives and coatings.
