The hydroxyl on the surface of the Si[O.sub.2] nanoparticles was reacted with 2-methyl-2-[(dodecylsulfanylthiocarbonyl) sulfanyl] propanoic acid and this esterification yielded a trithioester-capped Si[O.sub.2], which was used as a nanoparticle chain transfer agent (denoted as Si[O.sub.2]-CTA) to mediate the radical polymerization of isoprene to produce silicon dioxide-gra/r-polyisoprene nanoparticles (Si[O.sub.2]-g-PIP).
This is because fewer accelerators were adsorbed by the silanol groups of Si[O.sub.2]-g-PIP than by those of Si[O.sub.2] [35, 36], The reduction of the silanol groups was caused by the following two aspects: first, some of the silanol groups reacted with 2-methyl2-[(dodecylsulfanylthiocarbonyl)sulfanyl] propanoic acid to produce Si[O.sub.2]-CTA; second, many silanol groups were sheltered from the polyisoprene blocks of Si[O.sub.2]-g-PIP.
The major components analyzed in the liquid product include acetaldehyde, propanoic acid, acrylic acid, lactic acid, 2,3-pentanedione; minor products include acetic acid, ethanol, acetone, etc.
