| abstract | Synthetic resins are prepared by esterifying the free hydroxyl group or groups of a partial acetic acid ester of a di- or polyhydric alcohol with a resin acid such as abietic acid or colophony by heating the ester with the acid. A metal catalyst such as aluminium may be used. Suitable esters are mono- and di-acetin, glycol monoacetate and propylene glycol monoacetate. The resins, with or without the addition of solvents, plasticisers, dyes and pigments, and cellulose derivatives such as cellulose nitrate, acetate or propionate or methyl, ethyl and benzyl cellulose, may be used in liquid, plastic and solid compositions such as in the preparation of lacquers, films or sheets, artificial yarns, moulding compositions and adhesives especially in the manufacture of laminated glass. Suitable solvents include acetone, methylene ethylene dioxide, ethyl alcohol, benzene, ethylene dichloride, ethyl acetate, ethyl lactate, glycerol formal, tetrachlorethane, benzyl alcohol, diacetone alcohol. Suitable plasticisers include diphenylol propane, triacetin, dibutyl tartrate, diethyl phthalate, dimethyl phthalate, toluene sulphonamide, monomethylxylene sulphonamide and fire retardants such as brominated tricresyl phosphate. Gums or resins such as manila, acaroids, pontianak, kauri, dammar and shellac and synthetic resins such as phenol form ldehyde or diphenylolpropane formaldehyde resins may also be added. In an example monoacetin or diacetin is esterified with abietic acid in the presence of aluminium.ALSO:Solutions comprising cellulose derivatives and resins obtained by esterifying partial acetic acid esters of polyhydric alcohols with abietic acid may be employed as adhesives. |
