Abstract
Disclosed is a dental composition comprising a (meth)acrylic ester compound as the principal component and containing a polymerization initiator, which is characterized by having incorporated therein a grafted rubber obtained by polymerizing at least one ethylenically unsaturated monomer in the presence of a rubber. This dental composition can be cured to yield a cured product having excellent strength properties and, therefore, is particularly useful in applications such as a molar restoration material and a denture base resin.
Claims4
A dental composition comprising a (meth)-acrylic ester compound as the principal component, wherein the (meth)acrylic ester compound contains at least one polyfunctional (meth)acrylic ester compound, and containing a polymerization initiator, which is characterized by having incorporated therein a grafted rubber obtained by polymerizing at least one ethylenically unsaturated monomer in the presence of a multilayer composite rubber obtained by polymerizing at least an acrylate monomer in the presence of a latex selected from the group consisting of styrene resins and polybutadiene and wherein the multilayer rubber contains 60 to 90 parts by weight of acrylate rubber and wherein the grafted rubber is present in an amount of 0.01 to 10 parts by weight per 100 parts by weight of the (meth)-acrylic ester compound.
