    Abstract: A process of preparing a telechelic polyolefin is disclosed by performing steps 1a, 2, and 1b in this order in the presence of an olefin polymerizing catalyst and subsequently performing step 3 if necessary. Step 1a involves reacting the olefin polymerizing catalyst with a polar-group-containing olefin (C). Step 2 involves reacting the resultant compound of step 1a with at least one olefin (D) selected from ethylene and olefins having 3 to 20 carbon atoms n times wherein n is an integer of 1 or more, provided that when n is an integer of 2 or more, the olefins (D) used in the respective contact operations are different in kind or composition. Step 1b involves reacting the resultant compound of step 2 with the same or different polar-group-containing olefin (C). Step 3 involves chemically converting the Y? group in the general formula (II) to a different group.

  • Patent number: 8124693
    Abstract: Various novel block cationomers comprising polyisobutylene (PIB) and poly(2-dimethylamino)ethyl methacrylate) (PDMAEMA) segments have been synthesized and characterized. The specific targets were various molecular weight diblocks (PDMAEMA+) and triblocks (PDMAEMA+-b-PIB-b-PDMAEMA+) with the PIB blocks in the DPn=50-200 (Mn=3,000-9,000 g/mol) range connected to blocks of PDMAEMA+ cations in the DPn=5-20 range. The overall synthetic strategy for the preparation of these block cationomers comprised four steps: 1) Synthesis by living cationic polymerization of mono- and di-allyltelechelic polyisobutylenes, 2) End group transformation to obtain PIBs fitted with termini capable of mediating the atom transfer radical polymerization (ATRP) of DMAEMA, 3) ATRP of DMAEMA and 4) Quaternization of PDMAEMA to PDMAEMA+I? by CH3I. Kinetic and model experiments provided guidance to develop convenient synthesis methods.
