Document Type and Number:

Japanese Patent JP5259900

Kind Code:

B2

Abstract:

Copolymers obtained by polymerisation of a mixture of unsaturated ester comonomers derived from alkanols of various chain lengths, in presence of initiators containing transferable atom groups, transition metal catalysts and coordinating ligands for the transition metal. Copolymers (CP) obtained by polymerisation of unsaturated monomers with initiators containing a transferable atom group and transition metal catalysts in presence of coordinating ligands for the transition metals, using a monomer mixture comprising (a) 0-40 wt% unsaturated ester compound(s) of formula R 2>R 3>C=CR-COOR 1> (I), (b) 10-98 wt% unsaturated ester(s) of formula R 5>R 6>C=CR-COOR 4> (II), (c) 0-80 wt% unsaturated ester(s) of formula R 8>R 9>C=CR-COOR 7> (III) and (d) 0-50 wt% comonomers, in which R : H or methyl; R 1>1-5C alkyl (linear or branched); R 2>, R 3>H or -COOR'; R' : H or 1-5C alkyl; R 4>6-15C alkyl; R 5>, R 6>H or -COOR; R : H or 6-15C alkyl; R 7>16-30C alkyl; R 8>, R 9>H or -COOR'; R' : H or 16-30C alkyl Independent claims are also included for; (1) A concentrate for use as a lubricating oil additive, containing 15-85 wt% CP; (2) Lubricating oil containing CP; (3) Biodiesel fuel containing CP; (4) Method for the production of CP by adding all the monomers at the start; and (5) Method for the production of CP by adding the monomers continuously or in batches.
