PROCESS FOR PRODUCING COPOLYMERS Russian patent published in 1994 - IPC

Abstract SU 1793702 A1

FIELD: chemistry, particularly, synthesis of vibration-absorbing materials. SUBSTANCE: essence of this process resides in carrying out water-emulsion copolymerization of 76.8 to 81.8 percent by mass styrene and 18.2 to 23.2 percent by mass N-phenylmaleimide in presence of surfactant and 0.3 to 2.8 percent by mass of total sum of monomers of thioalcohol of general formula RSH, where R represents alkyl C4-C12. EFFECT: excellent starting stock for manufacture of vibration-absorbing materials. 1 tbl
