Organometallic reversible addition-fragmentation chain transfer reagents (RAFT reagents), processes of free radical polymerization employing the same and polymers with low polydispersity index obtained thereby. The process includes polymerizing at least one monomer with at least one initiator and at least one organometallic RAFT reagent to obtain polymers having terminal organometallic functional groups with low polydispersity index. In addition, the terminal organometallic functional group may be removed by subjecting the obtained polymer to elimination to provide the corresponding organic polymers.

Chain transfer reagent, free radical polymerization employing the same and resulting polymers

A polyolefin-based nanocomposite and a method of preparing the same are disclosed. The polyolefin-based nanocomposite is prepared by melt kneading a mixture including (A) 40-99.8% by weight of a matrix polymer of polyolefin; (B) 0.1-30% by weight of a polyolefin compatilizer containing polar reactive groups; and (C) 0.1-30% by weight of a layered clay material having a quaternary ammonium ion bonded to the surface thereof. The quaternary ammonium ion contains (I) at least one alkyl group having at least 15 carbon atoms; and (ii) a substitutent having &#x2014;Si&#x2014;O&#x2014;Si&#x2014;linkage and at least one terminal reactive group.
