The present invention provides methods for making polymerizable monomer compositions comprising purifying a (b) monomer mixture of (i) one or more monomers having at least two polymerizable vinyl groups and (ii) one or more monomers having a single polymerizable vinyl group as part of a (meth)acrylate ester group by any one or more of treating the monomer mixture in an activated porous alumina or silica column, sieve drying the monomer mixture in a vacuum followed by drying over dried molecular sieves having average pore sizes of from 2 to 20 Angstroms, freeze-pump-thaw (FPT) treating by freezing the monomer mixture in a vessel or container to a temperature below −75° C., degassing the monomer mixture by application of vacuum in the range of 102 to 10−2 Pa, sealing the vessel or container under vacuum, and thawing the composition to room temperature; and, combining in an inert gas atmosphere the resulting monomer mixture (b) with a composition (a) of quantum dots in dry form or organic solvent solution.
本发明提供了制造可聚合单体组合物的方法,包括通过在活化多孔氧化铝或二氧化硅柱中处理单体混合物,纯化(b)单体混合物,该单体混合物包括(i)具有至少两个可聚合乙烯基的一种或多种单体和(ii)具有作为(甲基)丙烯酸酯基团一部分的单个可聚合乙烯基的一种或多种单体、将单体混合物在真空中进行筛分干燥,然后在平均孔径为 2 至 20 埃的干燥分子筛上进行干燥,冷冻-泵-解冻(FPT)处理,将容器中的单体混合物冷冻到低于 -75°C 的温度,在 102 至 10-2 Pa 的范围内抽真空,使单体混合物脱气,在真空下密封容器或容器,并将组合物解冻至室温;以及,在惰性气体环境中将得到的单体混合物(b)与量子点组合物(a)的干燥形式或有机溶剂溶液结合。
