Degradation of vinyl polymer films upon exposure to chlorinated water: the pronounced effect of a sample’s thermal history

polystyrene and poly(styrene- co-butadiene)

0.2 to 0.08 M in NaClO

Poly(styrene-cobutadiene) was more reactive than polystyrene upon exposure to chlorinated water and the data clearly indicate that olefinic residues are an important reactive functional group under these conditions.

Polybutene-1 pipes exposed to pressurized chlorinated water: Lifetime and antioxidant consumption

Isotactic polybutene-1

(6.5G0.1),

≤3 ppm

The lifetime shortening in the isotactic poly(butene-1) pipes exposed to chlorinated water (0.5 - 3 ppm) was approximately by a factor of 10 with respect to that obtained in pure water. The lifetime shortening was significant even at low chlorine concentrations (0.5 ppm Cl) and a further increase in chlorine content led only to a moderate additional increase in the lifetime shortening.

chlorine dioxide (DOC)

Aging of polyethylene (PE) films in highly concentrated (80 - 100 ppm) chlorine dioxide (DOC) solutions at 20 and 408C for durations up to 1200 h has been studied by IR spectrophotometry, tensile testing, melt rheometry, and grafted chlorine titration. IR revealed a carbonyl growth indicating that DOC induces PE oxidation. Rheometry revealed the predominance of chain scissions, presumably linked to hydroperoxide decomposition. Tensile testing revealed an embrittlement process when the weight average molar mass MW approaches a critical value of 70 kg mol21, which agrees with a previous study of PE thermooxidation.
