POLYACRYLONITRILE SYNTHESIS METHOD Russian patent published in 2010 - IPC C08F120/44 C08F4/36 C08F2/02 

FIELD: chemistry.

SUBSTANCE: present invention relates to chemistry of high-molecular compounds and describes a polyacrylonitrile synthesis method through polymerisation of acrylonitrile in the presence of a peroxide initiator at high temperature, where the peroxide initiator used is germinal bishydroperoxides of general formula: , where R₁ = lower alkyl, R₂ = H or methyl, R₃ = H or lower alkyl, R₄ = H or lower alkyl, or R₁+R₄=CH₂CH₂ or CH₂C(R₅R₆)CH₂, where R₅ and R₆ = H or methyl, in amount of 0.05-0.5 wt % of acrylonitrile and the process is carried out at 50-60 °C in the monomer mass.

EFFECT: design of an efficient polyacrylonitrile synthesis method.
