摘要： COPOLYMERS OF ETHYLENE WITH VINYL MONOMERS, WHICH ARE DERIVATIVES OF VINYLTIN OF THE GENERAL FORMULA

CH2=CHSNR1R2R3

WHEREIN R1, R2, R3 ARE THE SAME OR DIFFERENT RADICALS: ALKYLS WITH THE NUMBER OF CARBON ATOMS FROM 1 TO 6, OR PHENYL, THE CONTENT OF ( -CH2-CH(SNR1R2R3)-) LINKS IN THE CPOLYMER BEING 1-30 MOL. PERCENT, AND THAT OF (-CH2-CH2- ) LINKS, 99-70 MOL. PERCENT. SAID COPOLYMERS ARE PRODUCED BY A METHOD WHICH INCUDED COPOLYMERIZING ETHYLENE WITH DERIVATIVES OF VINYLTIN OF THE ABOVESPECIFIED GENERAL FORMULA AT A MOLAR RATIO OF ETHYLENE TO ORGANOVINYLTIN MONOMERS EQUAL TO 20-98:80-2 RESPECTIVELY, UNDER A PRESSURE OF 50-3000 ATM., AT A TEMPERATURE OF 50-300* C., IN THE PRESENCE OF INITIATORS OF FREERADICAL TYPE. THE COPOLYMERS THUS PRODUCED CAN BE USED AS ANTIWEAR ADDITIONS TO LUBRICANTS.
