Abstract
Liquid polymers essentially of cis-1,4-butadiene are prepd. by reacting buta-1,3-diene with >=1 mono alk-l-ene (esp. but-1-ene) in the presence of a catalyst (RCO2) NiX (where X is halogen, and R is alkyl in which the C-atom adjacent the carboxylate gp. is substd. with >=1 F atom), pref. at reduced pressure and 30-120 degrees C. The prods. are used as softeners for thermoplastics, as hardening accelerators in coating compsns., as additives to adhesives, for lowering filtration and pour-point of liquid fuels and to improve the viscosity index of motor oils.
