HYBRID POLYMER NETWORK COMPOSITIONS FOR USE IN DENTAL APPLICATIONS

摘要

A dental appliance comprising a hard, shaped body having at least one portion comprising a polymerized blend of: A from 0% to about 50% of an uncrosslinked polymer capable of dissolving in component;B from about 0% to 50% of a mono functional polymerizable monomer;C from about 0% to 40% of a highly crosslinked polymer in the form of ground particles having average diameters up to about 500 microns;D from about 0% to 50% of a crosslinked polymer in the form of discrete particles having average diameters up to about 500 microns and being easily swellable by said monomer; and E from about 5% to about 35% of a di - or polyfunctional crosslinking agent.
