Patent number: 4151001Abstract: Compositions useful as substitutes for natural beeswax are disclosed. Such compositions comprise a reaction product obtained by reacting under esterification conditions (1) an alcohol containing from about 10 to about 22 carbon atoms, (2) a glycolic component selected from the group consisting of ethylene glycol, propylene glycol, polyoxyethylene glycol having a molecular weight from about 100 to about 1500, and polyoxypropylene glycol having a molecular weight from 150 to about 1025, and (3) a difunctional acid containing from about 7 to about 36 carbon atoms. The foregoing reaction product may be optionally mixed with other esters, or with minor amounts of natural beeswax.Type: GrantFiled: October 11, 1977Date of Patent: April 24, 1979Assignee: Akzona IncorporatedInventors: Gilbert L. Anderson, Jr., Frederick P. Siegel

Patent number: 4122057Abstract: Polyester plasticizers having improved low temperature properties are obtained by terminating the polyester with mixed chain-terminating agents. Mixtures of monobasic acids and monofunctional alcohols are employed for this purpose. The polyesters of this invention find particular utility as plasticizers for PVC homopolymers and copolymers.Type: GrantFiled: April 5, 1976Date of Patent: October 24, 1978Assignee: Emery Industries, Inc.Inventors: James Lamont, Robert D. Aylesworth, Bruce J. Beimesch

Patent number: 4108666Abstract: A photosensitive composition for a photoresist, which comprises (A) a compound having the following general formula: ##STR1## wherein Z is a cyclic dibasic acid anhydride moiety, R.sup.1 is an alkylene group having 1 to 3 carbon atoms, R.sup.2 is hydrogen or methyl, and R.sup.3 is hydrogen, methyl, ethyl or -CH.sub.2 X in which X is chlorine or bromine, (B) a photopolymerization sensitizer, (C) a polymer being capable of giving a film-forming property, (D) a chain transfer agent and (E) a thermal polymerization inhibitor; and a laminated photosensitive element which has a substantially dry photosensitive layer of the photosensitive composition. The composition and element are capable of giving a minute resist pattern which is excellent as an etching resist or metal plating resist and can be readily removed after etching or metal plating.Type: GrantFiled: March 11, 1976Date of Patent: August 22, 1978Assignee: Hitachi Chemical Co., Ltd.Inventors: Nobuyuki Hayashi, Asao Isobe, Katsushige Tsukada, Toshiaki Ishimaru

Patent number: 4086181Abstract: For inhibiting corrosion and scale on ferrous metal parts in a circulating water system there is added to the water in such system from 10 to 500 ppm of a partial ester of a polyfunctional acid having a free carboxylate, phosphonate or sulfonate group and another carboxyl group which is esterified with a polyoxyalkylated derivative of an alkyl, alkaryl, or alkenyl alcohol having a terminal hydrocarbon group of 8-20 carbon atoms. In some preferred embodiments there is added with the partial ester from 10 to 500 ppm of a dispersible oil which may also include a surface active agent for dispersing the oil in water. Preferred partial esters include partial esters of citric, malic, tartaric, maleic, adipic and phthalic acids partially esterified with an alkyl polyoxyethylene alcohol having 2 to 4 ethoxy groups.Type: GrantFiled: February 14, 1977Date of Patent: April 25, 1978Assignee: American Cyanamid CompanyInventors: Tzeng Jiueq Suen, Arthur James Begala, Jr., Martin Grayson
