| titleOfInvention | Multifunctional organic alkali metal initiator and its synthesis, anionic polymerized star polymers and their preparation |
| abstract | PCT No. PCT/CN96/00090 Sec. 371 Date Jun. 26, 1998 Sec. 102(e) Date Jun. 29, 1998 PCT Filed Oct. 17, 1996 PCT Pub. No. WO97/14722 PCT Pub. Date Apr. 24, 1997This invention relates to a multifunctional organic alkali metal initiator for the preparation of various kinds of star polymers by anionic polymerization, a process for making the initiator, a process using said initiator for making star polymers and the polymers obtained. The initiator can be represented by the formula: Ma (RMe)b, wherein M is selected from Sn, Ti, Al, Si and/or B; R is a hydrocarbyl group containing 8-100 carbon atoms, a=1-3, b=2.5-6.5, Me is an alkali metal which may be selected from Na and Li. The initiator was synthesized by reacting an organic alkali metal with a conjugated diene and/or a mono-olefin monomer, and then adding hetero-atom containing halide. The star polymer obtained has a radial molecular structure consisting of several macromolecular chain arms radiating from the initiator core, and its molecular weight distribution expressed by GPC presents a uniform singlet. |
