Weatherproofing substrates

Weatherproofing substrates. Sherno, Stanley A. (Aperm, USA). U.S. US 4413026 A 1 Nov 1983, 5 pp. Cont. of U.S. Ser. No.There are some reagents with their cas registry numbers 13463-67-7 and 12794-56-8 are used in this study. 279,062 abandoned. (English). (United States of America). CODEN: USXXAM. CLASS: IC: B05D003-02. NCL: 427407100. APPLICATION: US 82-395956 7 Jul 1982. PRIORITY: US 79-41592 23 May 1979; US 79-103438 14 Dec 1979; US 80-129249 11 Mar 1980; US 81-279062 30 Jun 1981. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Section cross-reference(s): 58 Heat-insulating inexpensive coatings suitable for waterproofing the exterior surface of roofs comprise aq. dispersions of foamed polystyrene [9003-53-6] in a thermoplastic latex contg. a thickener. The coating is applied in few layers, 1st of which contains relatively low amts. of the binder in contrast to subsequent layers. Thus, a coating was prepd. by blending hydroxyethyl cellulose [9004-62-0] thickener, ethylene glycol [107-21-1] antifreeze, Nopco NXZ [12794-56-8] defoamer, acrylic latex, 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate [25265-77-4] plasticizer, TiO2 pigment, ground limestone filler, and additives. Foamed polystyrene beads were added to the resultant blend in an amt. of 35 vol.%. .

Nonaqueous dispersion polymerization of vinyl monomers

Nonaqueous dispersion polymerization of vinyl monomers. Bhattacharyya, Bhupati R.; Ballweber, Edward G. (Nalco Chemical Co., USA). U.S. US 4420586 A 13 Dec 1983, 6 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: L08F002-14. NCL: 524769000.Several reagents with their cas registry numbers 89183-56-2 and 89213-71-8 are used here. APPLICATION: US 82-445326 29 Nov 1982. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Section cross-reference(s): 35 Nonaq., radical, dispersion polymn. in the absence of block or graft polymer stabilizers is carried out using water-sol. and -insol. monomers in C8-15 alcs. with 32 labile H atoms and 31 tertiary C atom. Thus, Texanol (2,2,4-trimethyl-3-hydroxypentyl isobutyrate) [25265-77-4] 600, acrylamide 20, acrylic acid 100, 2-hydroxyethyl methacrylate 40, N-methylpyrrolidone 20, Et acrylate 10, stearyl methacrylate 10, and AIBN 1 g were heated for 4 h at 60°, mixed with 0.15 g AIBN, and heated 1.5 h at 80° to give a copolymer [89213-73-0] contg. <0.4% unreacted monomer. The Brookfield viscosity of a 1.0% neutralized soln. was 200 cP. .
