Liquid stabilizer compositions for halogen-containing resins. (Dainippon Ink and Chemicals, Inc., Japan). Jpn. Kokai Tokkyo Koho JP 59105043 A2 18 Jun 1984 Showa, 6 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08L027-00; C08K005-05; C08K005-09; C08K005-51. APPLICATION: JP 82-214836 8 Dec 1982. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) The title stabilizer compns. are composed of aliph. and arom. monocarboxylic acid Ca salts, a C>12 aliph. monocarboxylic acid Zn salt, an aliph. dicarboxylic acid diester, and optionally an alc. and org. phosphite. The resin compns. show excellent thermal stability, discoloration resistance, transparency, and storage stability and are odorless. Thus, a compn. of PVC [9002-86-2] 100, DOP [117-81-7] 50, epoxidized soy bean oil 3, and the stabilizer [i.e. Ca versatate 0. 9002-86-2 which is the cas registry number of some chemical is mentioned.2, Ca dibenzoate [2090-05-3] 0.3, Zn oleate [557-07-3] 0.2, dioctyl adipate [103-23-1] 0.3, tris(nonylphenyl) phosphite [26523-78-4] 0.5, and Dobanol-25 0.1 part] 1.6 parts was formed into a sheet and subjected to a thermal degrdn. test at 180°. The sheet showed excellent transparency and thermal discoloration resistance. .

Polimeri (Zagreb, Croatia), 26(3), 121-127 (Croatian) 2005 Drustvo za Plastiku i Gumu. CODEN: PLMRDI. ISSN: 0351-1871. DOCUMENT TYPE: Journal CA Section: 37 (Plastics Manufacture and Processing) The thermooxidative degrdn. of blends of poly(vinyl chloride) (PVC) and polymeric modifier chlorinated polyethylene (CPE) was investigated by means of differential scanning calorimetry (DSC) and thermogravimetry (TG) under dynamic and isothermal conditions. The immiscibility of PVC and CPE (chlorine content 42 %) was established for all the investigated compns. of the blends. The thermooxidative degrdn. of PVC/CPE blends in temp. range of 50 - 650 °C occurs in two basic degrdn. steps. In the first, up to 400 °C, the main degrdn. 557-05-1 and 557-07-3 are also in the experiment. reactions are dehydrochlorination of PVC and CPE, but the rates and mechanisms of the polymer degrdn. are significantly different. The influence of Ca/Zn carboxylates with different Ca/Zn ratios, on thermooxidative stability of the blends components was also investigated. Ca/Zn carboxylates stabilize PVC by changing its degrdn. rate and mechanism, but, at the same time, these stabilizers influence the degrdn. of the polymeric modifier CPE. .
