Vinyl resin and resin composition

The present invention aims to provide a vinyl resin which, with a polyurethane resin, is capable of providing a film excellent in mechanical strength, weather resistance, solvent resistance, and water resistance. The vinyl resin (V1) of the present invention is obtainable by polymerizing monomer components including a monomer (X) represented by the formula (1):
wherein M1 is a hydroxy group or a residue of an active hydrogen-containing organic compound having a valence of 1 to 20 from which c number of active hydrogen atoms are removed; c is 1 if M1 is a hydroxy group, or c is an integer satisfying 1≦c≦(valence of M1) if M1 is a residue of an active hydrogen-containing organic compound having a valence of 1 to 20 from which c number of active hydrogen atoms are removed; R1 is an ethylenic unsaturated bond-containing group, and when the formula (1) includes multiple R1's, they may be the same as or different from each other; M2 is a hydroxy group or a residue of an active hydrogen-containing organic compound having a valence of 1 to 20 from which one active hydrogen atom is removed, and when the formula (1) includes multiple M2's, they may be the same as or different from each other, and M2 and M1 may be the same as or different from each other; L is a residue of an aromatic polycarboxylic acid having 3 or more carboxyl groups from which all the carboxyl groups are removed, the aromatic ring of L is constituted by carbon atoms, and each of the carbon atoms may optionally have a halogen atom and/or a substituent which is not a carboxyl group, but at least one of the carbon atoms has a hydrogen atom; a and b are each an integer of 0 or greater and they satisfy 2≦(a+b)≦(d−2), when the formula (1) includes multiple a's, they may be the same as or different from each other and at least one of c number of a's is not 0, and when the formula (1) includes multiple b's, they may be the same as or different from each other; and d is the number of hydrogen atoms bonded to the carbon atoms constituting the aromatic ring assuming that all the substituents including the carboxyl groups of the aromatic polycarboxylic acid are replaced by hydrogen atoms, in other words, the number of moieties capable of being replaced by a substituent on the aromatic ring.

Dibenzothiophene-based aromatic phosphine oxide compound and preparation method and application thereof

The invention relates to a dibenzothiophene-based aromatic phosphine oxide compound and a preparation method and application thereof. The invention solves the problems that an electrophosphorescent device has low efficiency and low brightness because the conventional electrophosphorescent material has serious concentration quenching and triplet-triplet annihilation effects. The structural general formula of the compound is that: X is H or a diphenylphosphine oxide group. The compound is obtained by the steps of: preparing a derivative from dibenzothiophene, n-butyllithium, tetramethylethylenediamine and diphenylchlorophosphine, dissolving the derivative into CH2Cl2, adding H2O2 and reacting. The invention also relates to application of the compound to organic electroluminescent light-emitting diode devices and application of the compound used as a main material of a luminescent layer. An electroluminescent blue-light and green-light main material with high triplet excited-state energy level and good carrier injection and transmission capacity is obtained by modifying the diphenylphosphine oxide group onto a chromophore parent through a C-P saturated bond; and the prepared device has high turn-on voltage, brightness and efficiency stability.

Methacrylates as stabilizers for polymer polyols

The present invention relates to ethylenically unsaturated macromonomers containing reactive unsaturated bonds and to methods for the preparation of these ethylenically unsaturated macromonomers containing reactive unsaturated bonds. These ethylenically unsaturated macromonomers are prepared by reacting a monofunctional compound conforming to a specific chemical formula with at least one alkylene oxide in the presence of at least one alkoxylation catalyst. The ethylenically unsaturated macromonomers conform to the chemical formulas described herein. The present invention also relates to preformed stabilizers comprising ethylenically unsaturated macromonomers, to processes for the preparation of these preformed stabilizers, to polymer polyols comprising these preformed stabilizers, and to these polymerizations comprising said preformed stabilizers. Preparation method of polyol. Polymer polyols containing ethylenically unsaturated macromonomers and methods for their preparation are also described.
