METHOD FOR PRODUCTION OF MODIFIED POLYISOPRENE COMPOSITION AND RUBBER COMPOUND UTILIZING IT Russian patent published in 2003 - IPC

Abstract RU 2215751 C1

FIELD: polymer materials. SUBSTANCE: invention relates to polyisoprene compositions and can be used in synthetic rubber industry, whereas the compositions are intended for use in rubber tire, rubber footwear, and cable industries. Modified composition is obtained by polymerization of isoprene in isopentane medium in presence of catalytic complex followed by deactivation and stabilization of polymerizate with phenol-amine resin obtained by condensation of alkylphenol with hexamethylenetriamine and N-isopropyl-N'- phenyl-p-phenylenediamine, which is then degassed and dried at 205-240 C, during which operation polyisoprene composition is modified. Rubber compound contains, weight parts: polyisoprene composition 100, zinc white 5.0, stearic acid 2.0, sulfur 2.0, sulfenamide C 0.8, carbon black 50.0 and shows cohesion strength 1.2 MPa. EFFECT: increased cohesion strength of rubber compound. 1 tbl, 8 ex
