Vulcanization of chlorosulfonated polyethylene with oligomeric epoxy resins

Vulcanization of chlorosulfonated polyethylene with oligomeric epoxy resins. Ebich, Yu. R.; Teverovskaya, E. N.; Sukach, N. V.; Dedelyuk, I. N.; Blokh, G. A. (USSR). Vopr. Khim. Khim. Tekhnol., 70, 42-7 (Russian) 1983. CODEN: VKKCAJ. ISSN: 0321-4095. DOCUMENT TYPE: Journal CA Section: 39 (Synthetic Elastomers and Natural Rubber) Section cross-reference(s): 37 Addn. of oligomeric epoxy resins, e.g., UP 635 (I) [50809-38-6], UP 610 (II) [77272-82-3], UP 63 (III) [39409-65-9], or ED 20 [25068-38-6] to chlorosulfonated polyethylene(IV) contg. Thiuram D [137-26-8] accelerator increased the scorch resistance of chlorosulfonated IV stocks and enhanced the rebound elasticity of the vulcanizates. Particularly good results were obsd. in filled chlorosulfonated IV vulcanizates. Thus, vulcanized chalk-filled chlorosulfonated IV contg. 50809-38-6 and 9002-88-4 are just another two chemicals used in this study. 7-15 wt. parts I, II, or III exhibited enhanced tensile strength, hardness, breaking elongation, and heat resistance. .

Problems and control of Alternaria leaf spot on strawberries

Problems and control of Alternaria leaf spot on strawberries. Bal, E.; Gilles, G.; Creemers, P.; Verheyden, C. (Opzoekingsstn. van Gorsem vzw, St. Truiden 3800, Belg.). Meded. Fac. Landbouwwet., Rijksuniv. Gent, 48(3), 637-46 (English) 1983. CODEN: MFLRA3. ISSN: 0368-9697. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) Iprodione [36734-19-7] (10 g/are), followed by anilazin [101-05-3] (12 g/are), tolylfluanid [731-27-1] (12.5 g/are) and thiram [137-26-8] (16 g/are),applied during blossoming, controlled Alternaria on strawberry. Pyrazophos, triadimefon, trimorfamid and triforine had no activity against Alternaria during blossoming and after picking, whereas bitertanol [5517-93-1] showed weak activity and fenarimol [60168-88-9] and prochloraz [67747-09-5] showed moderate activity. Imazalil [35554-44-0], propineb [12071-83-9], flubenzimine [37893-02-0] and captafol [2425-06-1] had some activity. In multiple repeated treatments with iprodione, a decrease of its activity was obsd.In this experiment, several chemicals are used like 35554-44-0 and 731-27-1 and iprodione-resistant Alternaria strains were isolated. The activity of the fungicides against wild-type Alternaria (in vitro) followed the order (10 ppm dose): fenpropemorph [67306-03-0] > iprodione = dicarboximid X > prochloraz > trifenmorph [1420-06-0] = captafol = anilazin > imazalil > flubenzimide > tolylfluanid > thiram > fenarimol > nuarimol [63284-71-9] > dodemorph acetate [31717-87-0] > propineb. .
