Mechanisms of antioxidant action: photostabilization of polypropylene using dithiophosphoryl compounds: effects of alkyl substituents
Mechanisms of antioxidant action: photostabilization of polypropylene using dithiophosphoryl compounds: effects of alkyl substituents. Al-Malaika, S.; Desai, P.; Scott, G. (Dep. Chem., Univ. Aston, Birmingham B4 7ET, UK). Plast. Rubber Process. Appl., 5(1), 15-18 (English) 1985. CODEN: PPAPDE. ISSN: 0144-6045. DOCUMENT TYPE: Journal CA Section: 37 (Plastics Manufacture and Processing) Evaluation of the effect of the alkyl substituents in Ni bis(O,O-dialkyldithiophosphates) (A) and dialkyl thiophosphoryl disulfides (B) on the photostability of Propathene HF200CV170 (polypropylene) [9003-07-0] showed that the photostability in the presence of the same molar concn. of different A reached an optimum for octyl deriv. On a wt. basis, Bu deriv. was superior to its higher homologs; the difference was attributed to the diln. of the antioxidant function in the mol. by the inert alkyl chain whose sole function is to increase soly. in the polymer. Optimum photoantioxidant activity clearly involved a compromise between chem. and phys. effects. Any A was superior to its corresponding B in stabilizing the polymer against UV light, although a similar trend was obsd. for the UV stability of the polymer with respect to the length of the alkyl chain. The most effective synergism between A and the com. UV absorber Cyasorb UV 531 [1843-05-6] was obtained when the latter was present in excess.

The photostabilized films under Florida weather conditions remained unchanged for 33 mo vs. 4-5 mo for unstabilized films. The highest weathering resistance was obtained for films stabilized with 0.75-1% Chimasorb 944.
