Abstract

A polymer composite comprising quantum dots; said polymer composite comprising: (a) quantum dots; (b) polymerized units of a first compound having at least one readily polymerizable vinyl group, a molecular weight from 300 to 20,000 and at least one continuous acyclic hydrocarbyl chain of at least five carbon atoms; and (c) polymerized units of a second compound having at least one readily polymerizable vinyl group and a molecular weight from 100 to 750; wherein a readily polymerizable vinyl group is part of a (meth)acrylate ester group or is attached directly to an aromatic ring, and the molecular weight of the first compound minus the molecular weight of the second compound is at least 100.
