Internally softened improved epoxy resin composition and coatings obtained therefrom (Internally flexibilized advanced epoxy rosin composltions and coatings therefrom)

摘要

The present invention relates to water or di- or trihydroxy substituted C ₁ -C ₈ hydrocarbons of one or more polyglycidyl ethers (A), one or more polyaromatic hydroxy compounds (B) and polyaromatic hydrides of the disclosed polybutylene glycols Containing residues of one or more polyglycidyl ethers (C) of the hydroxy compound, wherein almost all glycidyl ether residues of the polyglycidyl ethers of polybutylene glycols are glycidyl ether residues and aromatic hydroxy residues. Bound to the polyaromatic hydroxy compound through the reaction product of; bound to the respective polyaromatic hydroxy compound, wherein each polyaromatic hydroxy compound is poly-linked through the reaction product of the aromatic hydroxy moiety to the glycidyl ether moiety. One or more polyglycidyl ethers of butylene glycol or one or more of polyaromatic hydroxy compounds To most polyglycidyl ethers of the polyaromatic hydroxy compound; and to most of the polyglycidyl ethers of the polyaromatic hydroxy compound are bound to at least one polyaromatic hydroxy compound through the reaction product of the glycidyl ether residue with the aromatic hydroxy residue Each moiety of the polyglycidyl ether of the polyaromatic hydroxy compound is bound to one or more polyaromatic hydroxy compounds via reaction of the glycidyl ether moiety with the aromatic hydroxy moiety; polyaromatic hydroxy compound to polybutyl A polyaromatic sufficient to cause the molar ratio of polyglycidyl ether of ene glycol to be from about 2.0 to about 1.0 or more, such that the terminal residue of the resin is a glycidyl ether residue from the poly glycidyl ether of the polyaromatic hydroxy compound Polyglycidyl ethers of hydroxy compounds Present in the resin) is directed to a softened improved epoxy resin.
