The formation of sulphur-containing groups is considered in relation to attack on polyolefines by sulphuric acids and the mode of action of sulphur-containing antioxidants.

This is analogous to the splitting out of hydrogen chloride from poly(vinyl chloride). If the hydrofluoro-elastomers are used as seals, or sealants, in contact with metals such as titanium, the pres

Traditional methods based on carbonyl index or oxygen absorption have many disadvantages and sensitive techniques have been developed based on reactions with sulphur dioxide; these give insights regarding the sites of oxidative attack.
