Abstract
Polyepoxides of general formula <FORM:1006331/C3/1> wherein -->\sM is <FORM:1006331/C3/2> when terminal, and -CH2CHOHCH2- when internal-there being on average more than two glycidyl groups per molecule; <FORM:1006331/C3/3> wherein R is alkyl with 1 to 7 carbon atoms, chlorine or bromine; y is 0, 1 or 2, the ether linkages being in para position to the quaternary carbon atom when y=0; A is <FORM:1006331/C3/4> R1 and R11 being H or alkyl with 1-7 carbon atoms; and n is 1 to 5, may be prepared by reacting 1 to 10 equivalent weights of a polyglycidyl ether ester of formula <FORM:1006331/C3/5> with equivalent weight of polyhydric phenol of formula <FORM:1006331/C3/6> Examples 1, 2 describe the preparation of the intermediate polyepoxides by reacting 44-bis-(4 -hydroxyphenyl) pentanoic acid with epichlorohydrin. A list is given of other suitable pentanoic acid derivatives which may be used. Examples 3-6 describe the reaction of the polyepoxides of Examples 1 or 2 with 2,2-bis-(4 -hydroxyphenyl) propane. In Example 7 that polyhydric phenol is replaced by 2,21-bis-(4 -[b -hydroxyethoxy]phenyl) propane. A list is given of other suitable bisphenols. In Example 8, a product according to the invention is dissolved in methyl ethyl ketone, mixed with ethylene diamine and used to coat a steel panel. In Example 9 a product of the invention is mixed with coal tar pitch and diethylene tri-amine and used to coat a steel pipe line joint. The products may also be used to modify urea-frormaldehyde or phenol-formaldehyde resins, especially for interior coating of sheet metal cans. They may also be used to modify vinyl polymers or alkyd resins.ALSO:In Example 2, 4,4-bis-(4-hydroxyphenyl)-pentanoic acid is reacted with epichlorohydric to give the polyglycidyl ether-ester.ALSO:In Example 8, a product prepared by reacting 4,4-bis(4-hydroxyphenyl) pentanoic acid with epichlorohydrin is reacted with 2,2-bis(4-hydroxyphenyl) propane, dissolved in methyl ethyl ketone, mixed with ethylene diamine and used to coat a steel panel. The baked film had good resistance to acetone, alkalis and acids. In Example 9 a similar product was mixed with coal tar pitch and diethylene triamine and used to coat a steel pipe line joint. The products according to the invention may be used to modify urea-formaldehyde or phenol-formaldehyde resins particularly for coating the interiors of sheet metal cans.
