Studies of the effects of copper, copper(II) oxide and copper(II) chloride on the thermal degradation of poly(vinyl chloride)

Self-healing polymeric materials based on microencapsulated healing agents: From design to preparation

“…Second, ATRP involves numerous catalysts, which have to stay in the synthesized polymers, thereby critically influencing their workability and performance. Typically, the metal catalysts employed in ATRP accelerate material aging and subsequent degradation [257]. Moreover, the products of ATRP typically have a dark appearance that is due to the presence of transition metal compounds and that is therefore difficult to lighten for esthetic purposes.…”

Copper(0)-mediated radical polymerisation in a self-generating biphasic system

“…[11][12][13][14][15][16][17][18] A main drawback of conventional transition metalmediated polymerisation techniques in general (including Cu(0)/SET-LRP) is the presence of metal/copper complexes in the final polymer. Traces of metal salts could result in polymer degradation due to potential catalytic oxidation, 19,20 contribute to the presence of residual colour and may even contribute to biological toxicity. 21 A variety of different routes have been explored to decrease the amount of metallic residues.…”

Characteristics and mechanism of low temperature dehydrochlorination of poly(vinyl chloride) in the presence of zinc(II) oxide

“…Thermal decomposition of PVC in the presence of various metal oxides and metal chlorides have also been studied [7][8][9][10][11][12][13][14][15][16][17] and revealed that metal oxides such as ZnO [9,12], iron oxide [14] and zinc(II) chloride [16] accelerate decomposition of PVC to aromatic compounds. Zhang et al [12] reported based on thermogravimetric-mass spectrometry that ZnO reacts directly with PVC at 473 K, a lower temperature than that of thermal decomposition (>523 K) of pure PVC, and the only volatile product is water.…”
