摘要：1,248,641. Alternating copolymerization. BRIDGESTONE TIRE K.K. 14 Oct., 1969[14 Oct., 1968; 16 Oct., 1968; 18 Oct., 1968; 22 Oct., 1968; 8 Feb., 1969; 13 Feb., 1969; 7March, 1969], No. 50512/69. Heading C3P. Alternating copolymers are obtained bycopolymerizing (A) a conjugated diene with (B) a (meth)acrylonitrile or an α,#-unsaturatedcarboxylic acid ester in the presence of a catalyst prepared in the presence of (B) andcomprising (C) a transition metal compound of Group IV or V, (D) certain organometalliccompounds and, optionally, (E) a further component such as metal halides, free-radicalsystems or molecular weight regulators. The monomers are typically (A) butadiene orisoprene, and (B) acrylonitrile, n-butyl acrylate, or methylmethacrylate, and mixturesthereof. The catalyst components are typically (C) AlEtCl 2 , AlEt 3 , ZnEt 2 , Et2Cd, Et 2 Be,Et 3 B, AlEt 3 Cl or Al 2 Et 3 Cl 3 , (D) VOCl 3 , VCl 4 , VO(O - t-Bu)3, VOCl 2 , vanadylacetylacetonates, ZrCl 4 , TiCl 4 , (EtO) 5 Ta, zirconium chloroanilate, and Zr and Ti esters,

and (E) azobis-isobutyronitrile, t-butyl peroxide, Et 3 B-O 2 (as air), diisopropyl peroxy-dicarbonate, dimethylaniline, n-dodecylmercaptan, CBr 4 , (t-C 4 H 9 ) 2 S 2 , CHBr 3 , AlCl3 , SnCl 4 , Et 3 SnCl, ZnCl 2 , CdCl 2 , MgCl 2 . HgCl 2 , GaCl 3 , BeCl 2 and CaCl 2 . Theconjugated diene units are substantially trans-1,4. The polymers are rubbery and may bevulcanized.
