METHOD OF STABILIZATION OF EMULSION POLYMERIZATION RUBBERS Russian patent published in 1999 - IPC

Abstract RU 2130031 C1

FIELD: chemical industry. SUBSTANCE: method comprises adding stabilizer. Stabilizer is product of reaction of maleinized tall oil containing resin and fatty acids in 1-2:1 weight ratio with weight fraction of bonded maleic anhydride from 10 to 30% with para- aminodiphenyl amine at tall oil to para-aminodiphenyl amine weight ratio of 100:18-54. Stabilizer is added in amount of 0.10-5.0 weight part per 100 weight parts of natural rubber to latex as aqueous alkaline solution. EFFECT: effective stabilization of natural rubbers when adding small amounts of phenylene diamine type oxidant to natural rubber. 14 ex, 3 tbl
