Hydrophobic polyvinyl alcohol and method for preparing hydrophobic polyvinyl alcohol

The present disclosure provides a top emitting organic electroluminescent device including a first scattering layer, and a first electrode, at least one organic material layer, a second electrode and a second scattering layer formed on the first scattering layer sequentially. The first scattering layer contains a plurality of micro-particles that are 10 to 90 wt % of the first scattering layer.

Top emitting organic electroluminescent devices

A partially esterified epoxy resin and an epoxy resin composition applied with the same, and a method for preparing the composition are provided. The preparation method includes the following steps. A bifunctional epoxy resin and an anhydride are mixed and heated, wherein the number of equivalent moles of the bifunctional epoxy resin is greater than that of the anhydride, to form a partially esterified epoxy resin. A curing agent is mixed into the partially esterified epoxy resin to form a mixed solution. The mixed solution is cured to form the partially esterified epoxy resin composition.

The disclosure provides a thermosetting composition, including: (a) about 1-35 wt % of an oligomer, wherein the oligomer is obtained by reacting a liquid epoxy resin with an aromatic primary amine having four active hydrogen atoms, and the liquid epoxy resin and the primary amine have an equivalent mole ratio of 1:0.15-1:2.50; (b) about 5-10 wt % of a long chain resin; (c) about 50-80 wt % of an epoxy resin having at least two functional groups; and (d) about 5-15 wt % of a plasticizer.

Thermosetting composition

A sealant composition is provided. The sealant composition includes (a) an oligomer including an unsaturated mono-carboxylic acid modified bisphenol A epoxy resin and an unsaturated mono-carboxylic acid modified bisphenol F epoxy resin, wherein an equivalence ratio of the bisphenol A epoxy resin to the bisphenol F epoxy resin is 0.05:0.95 to 0.3:0.7, the bisphenol A epoxy resin has a melting point higher than 40&#xb0; C. and the bisphenol F epoxy resin has a melting point lower than 40&#xb0; C.; (b) an epoxy resin having at least two or more than two epoxy groups; and (c) a photoinitiator.

Sealant composition

An organic electroluminescent device. The organic electroluminescent device comprises a first barrier layer disposed on a substrate; organic electroluminescent elements disposed over the first barrier layer and encapsulated with a second barrier layer; and a getter layer disposed between the first and second barrier layers. Each of the first and second barrier layers includes an organic layer and an inorganic layer covering the top and sidewall surfaces of the organic layer, thus providing stacked inorganic sidewalls to hinder moisture and oxygen.
