Verfahren zur Herstellung von terpolymeren Harzen

Resins are obtained by the reaction of 1,4-bis (p-hydroxycumyl)benzene or 1,3-bis(p-hydroxycumyl) benzene with an epoxide resin prepared from 2,2-bis(p-hydroxyphenyl)propane and epichlorohydrin. The products may have either phenolic or epoxy end groups and, in a modification, resins with epoxy end g...

description Resins are obtained by the reaction of 1,4-bis (p-hydroxycumyl)benzene or 1,3-bis(p-hydroxycumyl) benzene with an epoxide resin prepared from 2,2-bis(p-hydroxyphenyl)propane and epichlorohydrin. The products may have either phenolic or epoxy end groups and, in a modification, resins with epoxy end groups are prepared by reacting the resins having phenolic end groups with epichlorohydrin in the presence of sodium hydroxide. The products are soluble in acetone and dioxan and may be cured by conventional curing agents such as diethylenetriamine, tolylene di-isocyanate, and phthalic acid. An urea-formaldehyde resin may be added as a plasticizer. For the purposes of comparison similar resins are prepared using, in place of the bis(p-hydroxycumyl)-benzenes, 2,2-bis(p-hydroxyphenyl)propane. The resins of the invention are useful in coating steel.ALSO:Films are cast on "Bonderized" (Registered Trade Mark) steel panels using composition of terpolymeric polyether resins obtained by reacting an epoxide resin derived from 2,2-bis(p-hydroxyphenyl)propane and epichlorohydrin with 1,4- or 1,3-bis(p-hydroxycumyl)benzene and a curing agent. The curing agent may be diethylenetriamine or tolylene di-isocyanate. The resin may be dissolved in an organic solvent such as acetone. The coating may be cured by heating.
