Abstract

The invention relates to the field of production of synthetic rubbers, in particular to an anionic (co-polymerization initiator, a method for preparing thereof and a method for preparing functionalized diene (co)polymers by using thereof. The present invention is to develop an anionic polymerization initiator having functional groups, characterized by a high long-term storage stability and an ability to reduce the time of polymerization (increase a polymerization rate) by 10-20%. The polymerization initiator is prepared by a method comprising reacting an amino alcohol with an alkali metal or an organolithium compound in a hydrocarbon solvent, with said amino alcohol being a mixture of products produced by reacting primary or secondary amine aniline with an epoxyalkane. The present invention also provides a process for preparing functionalized diene (co-)polymer rubbers characterized by a random distribution of their monomer units, a high content of vinyl units, such as 1,2-butadiene and/or 3,4-isoprene units (more than 50 wt. %), and a narrow molecular weight distribution (1.4-1.7) using said anionic polymerization initiator. Vulcanizates produced from the rubbers prepared according to the process are characterized with an improved combination of physico-mechanical and elastic-hysteresis properties.
