Advanced epoxy resin compositions are prepared by reacting a composition comprising (1) an aromatic hydroxyl-containing product resulting from reacting a composition comprising (a) at least one diglycidyl ether of (i) an oxyalkylated aromatic diol, or (ii) at least one compound having two hydroxyl groups per molecule in which the hydroxyl groups are attached to an aliphatic or cycloaliphatic carbon atom and which compound is free of aromatic rings; or (iii) a combination of (i) and (ii); and (iv) optionally a diglycidyl ether compound different from (i) and (ii); and (b) at least one compound containing two aromatic hydroxyl groups per molecule; (2) at least one diglycidyl ether of a compound containing two aromatic groups per molecule; (3) optionally, one or more compounds containing two aromatic hydroxyl groups per molecule; and (4) optionally, a monofunctional capping agent. The advanced resins are useful in coating compositions.

The present invention refers to active hydrogen-containing compositions comprising alkoxylated epoxy resin adducts useful in the preparation of rigid polyurethane foams. The active hydrogen-containing compositions comprising alkoxylated epoxy resin adducts of the present invention provide improved physical properties, such as, for example, friability. This invention also refers to prepolymers and foamed articles prepared therefrom.

A composition useful as an electrodepositable coating comprises a curing agent and an advanced epoxy resin prepared by advancing a diglycidyl ether of a dihydric phenol with an aromatic hydroxyl-containing reaction product of a diglycidyl ether of an oxyalkylated dihydric phenol and/or a diglycidyl ether of a (cyclo) aliphatic diol, optionally with a dihydric phenol and/or a monofunctional capping agent, combined with a diglycidyl ether of a dihydric phenol.

Epoxy resin advanced with diphenol/diglycidyl ether adducts

Epoxy resins and vinyl ester resins are prepared which contain a polymeric domain containing mesogenic or rigid rodlike moieties.

Liquid crystal/rigid rodlike polymer modified epoxy/vinyl ester resins

Novel advanced epoxy resins are disclosed which are the product resulting from (I) polymerizing in the presence of a catalytic quantity of a suitable polymerization catalyst (A) the reaction product of (1) a mixture consisting of (a) a diglycidyl ether of a dihydric phenol or a diglycidyl ether of a dihydric cyclohexanol and (b) a diglycidyl ether of a mono-, di-or polyetherdiol with (2) a compound containing both a group reactive with an epoxide group and a polymerizable ethylenically unsaturated group; with (B) a monomer mixture containing (1) at least one vinyl aromatic monomer, (2) a compound containing both a group reactive with an epoxide group and a polymerizable ethylenically unsaturated group and optionally (3) a hydroxyalkyl acrylate or methacrylate or an alkyl acrylate or methacrylate; and (II) advancing in the presence of a catalytic quantity of a suitable advancement catalyst, the product from (I) with (C) a dihydric phenol.

Novel advanced epoxy resins are disclosed which are the product resulting from (I) polymerizing in the presence of a catalytic quantity of a suitable polymerization catalyst (A) the reaction product of (1) a mixture consisting of (a) a diglycidyl ether of a dihydric phenol or a diglycidyl ether of a dihydric cyclohexanol and (b) a diglycidyl ether of a mono-, di- or polyetherdiol with (2) a compound containing both a group reactive with an epoxide group and a polymerizable ethylenically unsaturated group; with (B) a monomer mixture containing (1) at least one vinyl aromatic monomer, (2) a compound containing both a group reactive with an epoxide group and a polymerizable ethylenically unsaturated group and optionally (3) a hydroxyalkyl acrylate or methacrylate or an alkyl acrylate or methacrylate; and (II) advancing in the presence of a catalytic quantity of a suitable advancement catalyst, the product from (I) with (C) a dihydric phenol.

Rheology low gloss, high impact strength powder coating resins

Modified epoxy resins are prepared by the reaction of one or more epoxy resins with polycarbonate resins or oligomers. One or more monoalcohols and/or monophenols can also be used in the modification reaction. The epoxy resins also can be advanced by inclusion of a polyphenol during the reaction. The modified epoxy resins have a chain branching and/or crosslinking due to carbonate bonding of polycarbonate chain scission products to the epoxy resin. The epoxy resins are useful to make powder coatings with enhanced adhesion to metal and resistance to cathodic disbondment.

Polycarbonate modified epoxy resins

Polymer concrete compositions comprising an unsaturated thermosettable resin(s) and/or ethylenically unsaturated monomer(s), an aggregate component and a water absorbent polymer are cured to provide polymer concrete with enhanced adhesion to substrates, especially wet concrete. A primer or coating composition for concrete comprising a water absorbent polymer and an unsaturated thermosettable composition is also disclosed.
