摘要:
The present application is directed to a curable composition and a method for isolating a working area in a patient's mouth. The curable composition can include a borate-crosslinked polysiloxane, at least one ethylenically unsaturated monomer comprising at least two polymerizable groups, and an initiator.
摘要:
Dental compositions comprising an addition-fragmentation agent having the formula: wherein R 1 , R 2 and R 3 are each independently Z m -Q-, a (hetero)alkyl group or a (hetero)aryl group with the proviso that at least two of R 1 , R 2 and R 3 is Z m -Q-; Q is a linking group have a valence of m +1; Z is an ethylenically unsaturated polymerizable group; m is 1 to 6; each X 1 is independently -O- or -NR 4 -, where R 4 is H or C 1 -C 4 alkyl; and n is 0 or 1; at least one multifunctional monomer comprising at least two ethylenically unsaturated group; optionally an inorganic filler; and a redox initiator system; and the use thereof are described.
摘要:
The present invention relates to ceramer compositions capable of being cured to form antistatic, abrasion resistant ceramers. The ceramer compositions comprise a plurality of colloidal silica particles, a binder precursor, and an electrically conductive organic polymer, for example, polythiophene. The present invention also relates to ceramer articles, for example, ceramer coatings and shaped ceramer particles made from the ceramer compositions and to methods of making the ceramer compositions and ceramer articles.
摘要:
Free radically polymerizable synthons for preparing siloxane polyoxamide copolymers are prepared by reacting amine-terminated siloxane polyoxamide compounds with an isocyanate-functional (meth)acrylate, an isocyanate-functional vinyl-substituted aromatic compound, or a vinyl azlactone. These free radically polymerizable synthons can be used to prepare polymer compositions by combining the free radically polymerizable synthons with an initiator and initiating polymerization.
摘要:
Addition-fragmentation agents of the formula are disclosed having the following functional groups: 1) a labile addition-fragmentation group that can cleave and reform to relieve strain, 2) a free-radically polymerizable group, and 3) a surface-modifying functional group that associates with the surface of a substrate.
