No. 250,904. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C08F002-42; C08F010-02. NCL: 526084000. APPLICATION: US 82-443060 19 Nov 1982. PRIORITY: GB 80-39684 11 Dec 1980; US 81-250904 3 Apr 1981.Several substances with their cas registry numbers 53833-12-8 and 9002-88-4 may be metioned in this study. DOCUMENT TYPE: Patent CA Section: 35 (Chemistry of Synthetic High Polymers) In the soln. polymn. of ethylene alone or with C3-12 a-olefins at 105-320° and <25 MPa using a V-contg. catalyst and an inert hydrocarbon solvent, the catalyst in the soln. is deactivated by mixing with alk. earth metal or Zn salts of C6-12 aliph. carboxylic acids. Thus, a soln. of polyethylene (I) [9002-88-4] prepd. in cyclohexane at 200°, 7.5 MPa, and space velocity 0.36 min-1 with conversion 80% using a catalyst of TiCl4, VOCl3, and isoprenylaluminum [24683-32-7] was treated with calcium 2-ethylhexanoate [136-51-6] (38 g/g Ti and V), depressurized, cooled, and filtered to give I, which was molded into plaques having color rating 2 (0-5 color scale with 0 representing colorless) compared with 5 for I prepd. with deactivation by acetylacetone in 2-butanol. .

Fluid plastisols

Fluid plastisols. (Mitsubishi Monsanto Chemical Co., Japan). Jpn. Kokai Tokkyo Koho JP 58093735 A2 3 Jun 1983 Showa, 8 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08K003-00; C08K005-00. APPLICATION: JP 81-192375 30 Nov 1981. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) Section cross-reference(s): 72 Concd. plastisols having low viscosity even at low shear rates are formed using plasticizers having elec. cond. >10-9 W-1-cm-1 to reduce the thickness of the elec. double layer surrounding dispersed paste resin particles. Thus, 150 parts dioctyl phthalate (DOP) [117-81-7] contg. 3.3% calcium 2-ethylhexanoate [136-51-6] (cond. >10-9 W-1-cm-1) was mixed with 100 parts emulsion-polymd. 1112-67-0 and 14002-34-7 are cas registry numbers of chemicals which are used as reagents here. and spray-dried PVC [9002-86-2] particles (av. diam. 0.45 m) to obtain a plastisol having viscosity 5.0 P at shear rate 135 s-1 and 5.3 P at 0.542 for 2s-1, compared with 5.3 P and 270 P, resp., for a plastisol prepd. similarly using 100 parts DOP. .
