(SX) is capable of functioning as a reinforcing agent in
nitrile rubber (NBR), yielding a comparable tensile strength
to HAF black at similar filler volume fraction [11]. Itwas also
reported that the use of the xanthated starch could
enhance the mechanical and thermal stability properties of
the starch/rubber composites [12]. Since the functional
groups on surfaces of silica and starch are similar to some
extent, i.e., the presence of hydroxyl (OH) group as
depicted in Fig. 1, it is of great interest to apply the xanthate
reaction for the reduction of hydrophilicity on the silica
surfaces in the same manner as the silane coupling agent
treatment.
Therefore, the present work aims to modify the surfaces
of PSi by the use of a xanthate reaction in order to reduce
the hydrophilic characteristics of PSi via the reduction in
the amount of silanol groups on PSi surfaces. The influence
of degree of xanthation on viscoelastic behaviour, cure
characteristics and mechanical properties of the silica-filled
NR vulcanisates is also investigated.
