DE 3228861 A1 9 Feb 1984, 22 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C08L021-00; C08K005-06. APPLICATION: DE 82-3228861 3 Aug 1982. DOCUMENT TYPE: Patent CA Section: 39 (Synthetic Elastomers and Natural Rubber) Section cross-reference(s): 27 Cyclic enol ethers of alcs. with functionality 1-3 are nonstaining antiozonants for natural and synthetic rubbers.There are some reagents like 100-73-2 is used in this study. Thus, adding 0.7 g Al(OPr-iso)3 as a CCl4 soln. dropwise to 2.5 mol 3,4-dihydro-2H-pyran-2-carboxaldehyde [100-73-2] stirred at 35-40° and stirring for a total of 4 h gave 74% (3,4-dihydro-2H-pyran-2-yl)methyl 3,4-dihydro-2H-pyran-2-carboxylate (I) [3540-36-1]. Natural rubber vulcanizates contg. 4.0 phr I when exposed in air contg. 1 ppm O3 required 72 and 48 h for cracking at 10 and 60% elongation, resp., compared with ￡2 and ￡2, resp., without I. .

Preparation of a novel hydrophilic polyamide membrane by "casting polymerization" of bicyclic oxalactam and its permeability for alkali metal ions: Preparation of a novel hydrophilic polyamide membrane by "casting polymerization" of bicyclic oxalactam and its permeability for alkali metal ions. Sumitomo, Hiroshi; Hashimoto, Kazuhiko (Fac. Agric., Nagoya Univ., Nagoya, Japan). Kobunshi Ronbunshu, 34(10), 747-50 (Japanese) 1977. CODEN: KBRBA3. DOCUMENT TYPE: Journal CA Section: 35 (Synthetic High Polymers) Section cross-reference(s): 28 Casting a soln. of 8-oxa-6-azabicyclo[3.2.1]octan-7-one (I) [49831-29-0] in THF or Me2SO, contg. the K salt of pyrrolidone as initiator, onto a glass or steel surface gave a polyamide (II [51122-15-7]) membrane with high permeability towards alkali metal ions in water. I was prepd. in 3 steps from 3,4-dihydro-2H-pyran-2-carboxaldehyde (acrolein dimer) [100-73-2].
