Abstract

A polymer composite comprising quantum dots. The polymer composite comprises: (a) quantum dots; (b) a first polymer having a molecular weight from 1,000 to 100,000 and a solubility parameter from 12 to 17 (J/cm3)1/2; (c) a second polymer comprising polymerized units of a first compound comprising at least one readily polymerizable vinyl group and having a molecular weight from 72 to 500, wherein the second polymer has a solubility parameter from 16.5 to 20 (J/cm3)1/2; and (d) a third polymer comprising polymerized units of a second compound comprising at least two readily polymerizable vinyl groups and having a molecular weight from 72 to 2000; wherein the first polymer encapsulates the quantum dots; wherein a readily polymerizable vinyl group is part of a (meth)acrylate ester group or is attached directly to an aromatic ring.
