Studies on the decomposition of oxalates in polymers in connection with the preparation of metallopolymers with highly dispersed filling. Study of the decomposition kinetics of some oxalates in polymers by means of thermogravimetric and differential thermal analyses. Savitskii, A. I.; Korovskii, Sh. Ya.; Prosvirin, V. I. (Inst. Inzh. Grazhdanskoi Aviats., Riga, USSR). Kolloidn. Zh., 39(3), 485-93 (Russian) 1977. CODEN: KOZHAG. DOCUMENT TYPE: Journal CA Section: 36 (Plastics Manufacture and Processing) The presence of polyamide P68 [9008-66-6] during the heating of a mixt. consisting of powd. P68 and copper oxalate (I) [814-91-5] or nickel oxalate (II) [547-67-1] changed the kinetics of thermal decompn. of I and II, and the presence of I or II changed the sintering, melting, and thermal degrdn. of P68. II lowered the sintering and melting temps. of P68, whereas I or II, and the products of their decompn., increased the thermal stability of the mixts. Heating the mixts. of powd. P68 and I or II gave high-quality polymers filled with finely dispersed Cu or Ni.

Polymer mixtures containing a vinyl chloride polymer and copper oxalate

Polymer mixtures containing a vinyl chloride polymer and copper oxalate. McRowe, Arthur Watkins (Goodrich, B. F., Co., USA). Ger. Offen. DE 2700656 14 Jul 1977, 8 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C08L027-06. PRIORITY: US 76-648277 12 Jan 1976. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) Cu oxalate [814-91-5] was added to PVC [9002-86-2] to inhibit burning and smoke formation during exposure to flame. The Cu oxalate did not affect the color and mech. properties of the PVC. Thus, the addn. of 2% Cu oxalate to PVC caused a 75% decrease in the formation of smoke during exposure to flame.
