3. A dental composite restorative system, comprising:

a polymerized composition formed by polymerization of a monomer composition, the monomer composition, comprising:

one or more functionalized vinylbenzyl components of the formula

wherein n is an integer equal to or greater than 1, and one or more R functional components, and

ether links connecting the one or more functionalized vinylbenzyl components and the one or more R functional components,

wherein the one or more R functional components are selected from a first group consisting of one or more hydroxyl methyl (—CHOH—) moieties and/or derivatives thereof, one or more ethoxy (—CH 2 —CH 2 —O—) moieties and/or derivatives thereof, and one or more benzene derivatives and from a sixth croup consisting of:
