NON-COLORING THERMOSTABILIZER OF SYNTHETIC ISOPRENE RUBBER HAVING HIGH CONTENT OF CIS-1,4 UNITS |
| 摘要 |
FIELD: organic chemistry. SUBSTANCE: use of the present invention promotes higher efficiency of thermostabilizers and widens range of polymer stabilizers. Compound is prepared by condensation of hydroquinone with <EMI ID=0.300 HE=3 WI=9 TI=CHI>- tetramethylmethylene bis-amine (bis-amine) at hydroquinone to bis-amine molar ratio of 1:2.1-5.0 in organic solvents. EFFECT: improved properties of the non-coloring thermostabilizer of synthetic isoprene rubber. 3 tblw |
