Patent GB-419675-A (GB)
Title: Improvements in or relating to the manufacture of conversion products of casein
Filed: 1933-05-16
Abstract: Ester-like conversion products of casein are obtained by reacting an alkylene oxide with a neutral or weakly acid aqueous suspension of casein until the product exhibits an alkaline character after neutralization of the acid if employed, for example, by ammonia. Water-soluble fatty acids, such as acetic acid, are preferred. Ethylene, propylene or butylene oxide, glycide, or mixtures of alkylene oxides obtained by conversion of commercial mixtures of unsaturated aliphatic hydrocarbons may be employed.  In the case of ethylene oxide, 10--50 per cent, and generally 20--30 per cent thereof by weight of the casein may be used.  Reaction may be effected up to 90 DEG  C., 40--80 DEG  C. being preferred.  The products may be employed in the production of adhesives and shaped artificial masses, and for sizing and finishing purposes in the textile and related industries.  They are soluble in dilute acids, for example, 2 or 3 per cent acetic acid.

Title: Polyepoxy ethers of polyhydric phenols and cured products obtained therefrom
Inventor: KRIMM HEINRICH
IPC: C07C45/48
Filed: 1965-04-07
Abstract: Epoxy resins having good dimensional stability at high temperature are polyglycidyl ethers of a polyhydric polynuclear phenol having 3 or more OH groups which is the reaction product of a bis-(4-hydroxyphenyl)-alkane with one or more moles of a p-alkenyl phenol, substantially all of the hydroxy groups of the polynuclear polyhydric phenol being etherified by glycidyl groups. An example is a polyglycidyl ether of 2,4-bis-(4-hydroxycumyl)-phenol, especially bis-(4-hydroxycumyl)-bis - (4 - hydroxyphenyl) - 2,2 - propane having the two 4-hydroxycumyl groups bound in the ortho position to at least one hydroxyl group of the 4 - hydroxyphenyl radicals. The polyglycidyl ether may be the reaction product of 1 mole of a bis-(4-hydroxyphenyl)-alkane with 1 to 2 moles of a p-alkenyl phenol, especially the reaction product of 1 mol of 2,2-bis-(4-hydroxyphenyl)-propane with 1 to 2 moles of p-isopropenyl phenol.  The polyglycidyl ethers may be prepared by dissolving a bis-(monohydroxyarylalkane) the aromatic group of which is substituted by a hydroxyphenyl alkylene group in epichlorohydrin using 2 to 20 moles of the latter per phenolic OH in the polyhydric phenol using an alkali metal hydroxide as catalyst and heating; up to 0.5% by volume of water may be added to the soln. formed.  Cured insoluble products may be obtained by reacting one or more of the polyglycidyl ethers with an epoxy resin curing agent, e.g. an amino compound or the anhydride of a polybasic acid.  Cured products may also be obtained using a mixture of polyglycidyl ethers according to the invention with a polyglycidyl ether of a bis-(hydroxyphenyl)-alkane.  The polyhydric polynuclear phenols used as starting materials may be prepared by the methods of either Specification 963,294 or 980,278.
