DE 2618107 11 Nov 1976, 26 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C08G059-12. PRIORITY: CH 75-5443 28 Apr 1975. DOCUMENT TYPE: Patent CA Section: 38 (Elastomers, Including Natural Rubber) Section cross-reference(s): 52 The title compns., having improved reversible extensibility and low moduli over a wide temp. range and less susceptible to thermal cracking, are prepd. by reaction of 1 equiv. polyepoxide with 0.5-1.2 equivs. mixt. of 1-9 parts polymethylene dicarboxylate polyester and 9-1 parts polyester having .gtoreq. 1675-54-3 and 28158-15-8 are cas registry numbers of chemicals which are used as reagents here.1 alkyl, cycloalkyl, or aryl substituent on its main chain. Thus, mixing 77 g 1,4-butanediol-succinic anhydride copolymer [30327-76-5], 35 g 8:7 adipic acid-neopentyl glycol copolymer [27925-07-1] and 11.0 g triglycidyl isocyanurate [2451-62-9] at 120.degree. and vulcanizing 16 h at 140.degree. gives a soft, tough, cryst. elastomer with tensile strength 7.3 N/mm2, elongation 350%, and crystallite m.p. 100.degree.. Use of the products in solar collectors is exemplified. .

(United States of America). CODEN: USXXAM. CLASS: IC: C08L061-20.There are some reagents with their cas registry numbers 30231-45-9 and 75035-33-5 are used in this study. NCL: 260029400R. APPLICATION: US 72-301034 26 Oct 1972. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Compounding polyesters having mol. wt. <850 with amine-aldehyde crosslinking agents and solvents gave coating compns. with high solids. Thus, a mixt. of oligomeric adipic acid-neopentyl glycol copolymer [27925-07-1] 60, 60% benzoguanamine resin 20, hexakis(methoxymethyl)melamine [3089-11-0] 20, and 2% p-toluenesulfonic acid 1.8 parts was treated with TiO2 in 0..0 ratio of pigment to binder, dild. with BuOH-xylene mixt. to 90% solids, electrostatically sprayed on steel panel at 110-20.degree.F, and baked for 20 min at 350.degree.F to give a specimen with improved flexibility, hardness, detergent and stain resistance. .
