METHOD OF PRODUCING HIGHLY CONCENTRATED POLYMER SUSPENSIONS Russian patent published in 2017 - IPC C08F112/08 C08F2/32 

Abstract RU 2610272 C1

FIELD: chemistry.

SUBSTANCE: invention relates to methods of producing aggregarively stable polymer suspensions. The method of producing aggregatively stable polymeric suspensions is proposed, with a narrow particle size distribution, with a polymer content in the polymer suspension above 15%, using αω-bis (trimethylsiloxy) polidimetilmetil (3-aminopropyl) siloxane or α,ω-bis (trimethyl-siloxy)polidimetilmetil (10-karboksidetsil) siloxane in an amount of 0,75-1,80 wt % per monomer as a reaction system stabilizer.

EFFECT: invention enables to obtain aggregatively stable polymer suspensions with a narrow particle size distribution, containing a significant amount of polymer (over 15%), with a relatively small content of the stabilizer (0,75-1,80 wt % per monomer).
