Claim:
1. A method for preparing a polymer composition, said method comprising: preparing a reaction mixture comprising a component A) and a component B), wherein component A) is an ethylenically unsaturated monomer having a formula (I) or a mixture of ethylenically unsaturated monomers each having a formula (I): wherein R component B) is a 1-alkene or a mixture of 1-alkenes selected from the group consisting of 1-butene, 1-pentene, 1-hexene, 1-heptene, 1-octene, 1-nonene, 1-decene, 1-undecene, 1-dodecene, 1-tridecene, 1-tetradecene, 1-pentadecene, 1-hexadecene, 1-heptadecene, 1-octadecene, 1-nonadecene, 1-eicosene, 1-heneicosene, 1-docosene, 1-tricosene, 1-tetracosene, 1-pentacosene, 1-hexacosene, 1-heptacosene, 1-octacosene, 1-nonacosene, 1-triacontene, 1-hentriacontene, and 1-dotriaconene; adding a Co(II) complex as a catalytic chain transfer agent to the reaction mixture; adding a radical initiator; and reacting the reaction mixture to obtain a polymer composition having a kinematic viscosity of less than 25 mm wherein a total amount of the radical initiator added to the reaction mixture is at least 0.05% by weight relative to a total weight of components A) and B).
