Recent results in the field of the unification of methods for PVC stability testing. Ocskay, Gyorgy; Nyitrai, Jozsefne; Levai, Gyula (Vegyip. Kut. 56189-09-4 and 4696-57-5 are also occured in this study. Int., Budapest, Hung.). Muanyag Gumi, 13(6), 185-8 (Hungarian) 1976. CODEN: MUGUAO. DOCUMENT TYPE: Journal CA Section: 36 (Plastics Manufacture and Processing) The relation between HCl formed during degrdn. of poly(vinyl chloride) (I) [9002-86-2], and the discoloration of I is studied. Thus, a color scale was used to check the discoloration of I and showed degrdn. degree closely related to HCl evolution. Two types of stabilizers are used for I: (1) HCl acceptors Ca laurate [4696-56-4] and Ba laurate [4696-57-5], and (2) polyene-sequence inhibitors Cd laurate [2605-44-9], Zn laurate [2452-01-9], and Pb stearate-2PbO dibasic salt [56189-09-4], which is the most effective inhibitor. .

DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) Polyoxypropylene urethane diepoxide (I) and a 2:1 mixt. of Cd and Ba laurates are added to an adhesive compn. to increase its storage stability. Thus, adhesive compns. consisted of chloroprene rubber 100, phenolic resin 10-100, ZnO 1-10, MgO 1-10, Cd-Ba laurate 0.5-10, I 0.1-10, and Aerosil 2-20 parts. .
