Synthesis and Properties of Some Characteristic Elastomers

Abstract

Along our studies, three sorts of characteristic elastomers are described in this review focusing on their synthesis, structure and properties.

  1. (1)

    A novel moisture-curable rubber and a high performance lignin-reinforced rubber with good processability were obtained by using newly developed 1-chloro-1,3-butadiene — 1,3-butadiene rubber (CB-BR) derived from the copolymerization of 1-chloro-l,3-butadiene (CB) and 1,3-butadiene by emulsion process.

     
  2. (2)

    The ionene-type viologen elastomers having poly(butadiene-co-acrylonitrile) (NBV) were obtained by the reaction of α,α’-dichloro-p-xylene (DCX), 4,4’-bipyridine (BP) and dimethylamine-terminated liquid nitrile rubber (AT-NBR). The tensile properties of these elastomers were found to depend upon the number of cation-site in a structural unit of the ionene, and to attain 46 MPa in tensile strength and 340% in elongation at break without any reinforcement and vulcanization.

     
  3. (3)

    Two sorts of ABA type liquid crystalline elastomers terminated with mesogenic groups were synthesized. The polymeric segment of B is polyolefin with molecular weight of about 2500. Mesogenic groups of A carring two or three phenylene groups combined by ester linkage, were prepared by the reaction of terephthalic acid and p-hydroxybenzoic acid. These polymers were liquid crystalline and could be formed into elastic films. Their thermal and mechanical properties were clarified.
