    Notes: Abstract This paper summarizes our research results on the synthesis of polyboranes and their applications in the functionalization of polyolefins. The method involves the borane monomers and transitional metal catalysts, such as Ziegler-Natta and metathesis catalysts. Our results show that most trialkylboranes are stable to a broad range of transitional metal catalysts. The borane-containing olefins can be homo- or copolymerized with olefins to the corresponding polyborane homo- and copolymers. The molecular weights of polyboranes are usually very high. Some of the reasons are attributed to the good solubility of polyboranes in hydrocarbon solutions during the polymerization processes. In turn, the borane groups in polymers are easily converted to other functional groups, such as hydroxyl groups, under mild conditions. Some high molecular weight functional polyolefins have been prepared with unique polymer structures, such as isotactic comb-like functional polymers, block copolymers, and alternating functional copolymers.

    Functionalization of polypropylene by hydroboration (1993)
    Bognor Regis [u.a.] : Wiley-Blackwell
    Journal of Polymer Science Part A: Polymer Chemistry 31 (1993), S. 2759-2763

    Notes: This article relates to functionalized polypropylene with high molecular weight and high crystallinity. The chemistry involves the hydroboration of poly(propylene-co-1,4-hexadiene) with borane reagents, such as diborane and 9-BBN. In turn, the borane-containing polymers are very versatile and can be easily converted to various functionalized polymers under mild reaction conditions. Despite the heterogeneous reaction conditions, both hydroboration and interconversion reactions were very effective using appropriate solvents. Apparently, the double bonds in the side chains are located in the amorphous phase and are ready for reaction with reagents. Overall, this functionalization process preserves the molecular weight and most of the crystallinity of poly(propylene-co-1,4-hexadiene). © 1993 John Wiley & Sons, Inc.
