, The films were prepared using organosoluble precursors, namely bismuth xanthates
for [Bi.sub.2][S.sub.3] and trimethylsilyl cellulose for cellulose.
Key statement: Process for producing a rubber composition comprising a rubber component (A) comprising at least one selected from natural rubbers and synthetic diene rubbers, a filler containing an inorganic filler (B), a silane coupling agent (C), and at least two kinds of chemical agents (D) and (E) selected from guanidines, sulfenamides, thiazoles, thiurams, dithiocarbamates, thioureas and xanthates
, wherein the rubber composition is kneaded in a plurality of stages wherein, in the first stage (X) of kneading, the rubber component (A), all or a portion of the inorganic filler (B), all or a portion of the silane coupling agent (C), and at least two kinds of the chemical agents (D) and (E) are added and kneaded.

Poly(vinyl acetate) (PVA) was grafted by CNCs (CNC-g-PVA) via surface initiated reversible addition-fragmentation chain transfer and macromolecular design via the interchange of xanthates
are created through the reaction of an organic substrate which contains hydroxyls with carbon disulphide; because of this, an increase of the biosorbent's affinity for Pb(II) is expected [21, 22].
(dithiocarbonate) were used as collector for flotation of galena and sphalerite minerals instead of less powerful Aero floats (dithiophosphates).
can form bidentate, monodentate, or network solids, showing a wide range of coordination behaviour [3-6].
