Hard, waxy ethylenically-polymerised telomer prodn. - using (2)-tert:butylazo-(2)-cyanobutane as free radical-generating initiator and prod. used as additive to grease or lubricating oil
Hard, waxy ethylenically-polymerised telomer prodn. - using (2)-tert:butylazo-(2)-cyanobutane as free radical-generating initiator and prod. used as additive to grease or lubricating oil
Ethylene is reacted with a telogen (e.g. methanol, ethanol, butanol, acetone, acetoaldehyde or polyethyleneoxide) in gas phase in the presence of a polymerisation initiator generating free radicals, i.e. 2-t-butylazo-2-cyanobutane of structural formula t-Bu-N=N-C(CH2(C2H5)CN.
