Abstract:
Liquid crystalline (meth)acrylates of the invention include at least three rigid rod-like moieties. One of these moieties is comprised between the (meth)acrylate rests and further two moieties are bonded as side chains. The liquid crystalline (meth)acrylates polymerizable using redox initiators and/or photo intiators. The (meth)acrylates of the invention polymerize quantitative and with very low volume shrinkage of less than 2.5 percent. The invention provides a polymerizable compound within the scope of general formula (I). These compounds are used in dental compositions and methods of use thereof.
Abstract:
The invention describes a low shrinking polymerizable dental material, comprising a mixture of a polymerizable resin, a polymerizable monomer, a polymerization initiator and/or sensibilizer and a filler in a content of about 20 to about 85 percent. The volumetric shrinkage during polymerization is less than about 1.5 Vol.-%due to its rheopex behavior.
