摘要:
Carbosilane-containing polymers (including oligomers) having the following structural features: greater than one repeat unit; at least 4 Si-arylene bonds; at least 1 (meth)acrylate moiety, Si—H moiety, or both; no Si—O bonds; preferably at least 4 silicon atoms; wherein 2 silicon atoms are separated by one arylene group in each repeat unit.
摘要:
An adhesive composition comprising an emulsion polymer which comprises a (meth)acrylate copolymer and silica nanoparticles is described. The addition of the nanoparticles results in a significant increase in the overlap shear properties.
摘要:
Described is a pre-adhesive, curable composition comprising an acid-functional (meth)acrylate copolymer and a novel (meth)acryloyl-aziridine crosslinking agent, which when crosslinked provides a pressure-sensitive adhesive composition.
摘要:
Initiators for atom transfer radical polymerizations are described. The initiators have an azlactone or ring-opened azlactone moiety to provide telechelic(co)polymers.
摘要:
Carbosilane monomers that include the following structural features: at least two Si-arylene bonds; at least one (meth)acrylate moiety; no Si—O bonds; and preferably at least two silicon atoms.
摘要:
An adhesive composition comprising an emulsion polymer which comprises a (meth)acrylate copolymer and silica nanoparticles is described. The addition of the nanoparticles results in a significant increase in the overlap shear properties of the adhesive while maintaining the peel adhesion.
摘要:
Hydrophilic compositions are described, which are prepared from a first oligomer containing pendent polymerizable groups and pendent hydrophilic groups, crosslinked with a co-reactive second component oligomer possessing photoinitiator groups. The compositions may be used as in preparation of hydrophilic gel coatings or layers for medical devices.
摘要:
A curable composition is described comprising a Michael donor component, a polyacryl component, and 1) an ethylenically unsaturated monomer having a reactive azlactone functional group, or 2) an ethylenically unsaturated monomer having a reactive ring-opened azlactone functional group. A telechelic polymer that is the reaction product of these components is also described.
