Degradation of rubber vulcanizates in the presence and absence of air as well as in
presence of ozone is reviewed in this paper. The paper also outlines the means to overcome …

The developments on long-term protection of rubber against aerobic aging are reviewed.
Although conventional antidegradants such as N-isopropyl-N'-phenyl-p-phenylenediamine …

The objective of the investigations presented in this thesis is to develop new long-lasting
antidegradants and to gain a better insight in the protection mechanism of these products. A …

Atmospheric ozone degrades polydiene rubbers by reacting with main chain unsaturation to
cause chain scission and a diminished surface strength. When the rubber is exposed above …

Rubber (IR or BR) vulcanizatcs containing DOPPD antiozonant have been aged under
ozone, and the soluble constituents have been removed by acetone extraction. Small …

The cracking of rubber by atmospheric ozone is now a well-known phenomenon and for a
number of years rubber scientists and technologists have devoted considerable effort to …

The current technology in ozone protection of rubber compounds is reviewed. The topics
covered are both static ozone protection involving the use of paraffin wax and the dynamic …

In the last few years several reviews and books have been published on the aging of
elastomers, but the overall view which they present of the oxidation of natural rubber and its …

This work reports a direct surface analysis of ozonization of vulcanized NR compounds by
ATR. On ozonization of a vulcanized NR compound without clay filler or AO a degraded …

The mechanical properties of a vulcanizate of a blend which comprises both a high-diene
rubber such as NR and an ozone-resisting concentration (at least 30 to 40 wt.% of the …
