Abstract:
A pattern article comprising a copolymer having polymerized units derived from a cleavable crosslinking monomer, to which a pattern is imparted by the release of incipient acid from a thermal acid generator or photoacid generator. The selective release of the acid provides a pattern of high crosslink density and low crosslink density as result of the incipient acid cleaving a portion of the crosslinks.
Abstract:
Addition- fragmentation agents having the following functional groups: 1) a labile addition- fragmentation group that can cleave and reform to relieve strain, 2) at least one high refractive index group, and 3) at least one ethylenically unsaturated, polymerizable group are described.
Abstract:
A polymerizable emulsion compositions comprising an oil phase having a (meth)acrylate copolymer, a plasticizer, a non-reactive (meth)acrylate copolymeric stabilizer; and a continuous aqueous phase comprising a buffer, non-polymerizable surfactant; and an oil- or water soluble initiator is described.
Abstract:
A Addition-fragmentation oligomers containing allylic disulfide groups are described. The oligomers may be added to polymerizable compositions to provide labile crosslinks that can cleave and reform during the polymerization process.
Abstract:
According to various embodiments of the present disclosure, a composition includes about 5 to about 40 parts by weight of a solute copolymer component. The solute component optionally has one T g or T m of at least 25°C. The composition further includes about 60 to about 95 parts by weight of a solvent monomer. The solvent monomer component includes (meth)acrylate monomers and a multifunctional acrylate. The sum of the solute copolymer component and the solvent monomer component is 100 parts by weight. The composition further includes about 5 to about 100 parts of a plasticizer, relative to the 100 parts.
Abstract:
A self-wetting adhesive composition is described comprising the reaction product of a low T g (meth)acrylate solute copolymer component; a low T g solvent monomer solvent monomer component comprising low T g monomers, a multifunctional acrylate; and a polymerizable siloxane copolymer having at least one polydiorganosiloxane segment and at least on oxyalkylene segment.
Abstract:
The disclosure describes a curable composition comprising a first oligomer having a plurality of polymerizable groups; a second component comprising alkylene oxide repeat units and terminal polymerizable groups, a solvent monomer component; and a photoinitiator. The curable composition may be used as an adhesive in optical applications.
Abstract:
Multilayer films and adhesive tapes that include such films, wherein the multilayer films include plasticized polyvinyl chloride and optionally one or more fillers.
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.
Abstract:
This disclosure provides novel adhesive compositions comprising a highly crosslinked and plasticized low T g (meth)acrylic copolymer that are self-wetting when applied to a substrate, and peelable therefrom.
