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:
The invention features compositions comprising at least one monomer that comprises a cyclic dithiane moiety attached to a (meth)acryloyl moiety. The composition may optionally contain additional polymerizable compounds, such as ethylenically unsaturated compounds, that are typically used in dental compositions.
摘要:
A gel material and medical articles including such material, wherein the transparent gel material includes a polymerized poly(alkylene oxide) macromonomer that, prior to polymerization, is free-radically polymerizable, multifunctional (preferably difunctional), and has an average molecular weight of at least about 2000.
摘要:
The present invention is directed to dental compositions that can be used as adhesives for bonding a dental material to a dental structure surface and/or as a dental restorative material. The dental composition is preferably applied to a dental structure surface under conditions effective to etch the dental structure surface.
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:
The present invention provides crosslinkable compositions useful in the preparation of hydrophilic gels, and are prepared from polymers having pendent hydrophilic groups, and pendant Michael donor groups, and crosslinked by polyacryl Michael acceptor compounds.
