METHOD FOR PRODUCTION OF LIGHT UNSATURATED PETROLEUM-POLYMER RESIN Russian patent published in 2004 - IPC

Abstract RU 2221815 C2

FIELD: polymer production. SUBSTANCE: petroleum-polymer resin particularly suitable in production of varnish-and-paint materials is prepared via catalytic polymerization of fraction 130-190 C of oil feedstock pyrolysis product carried out in presence of 1.5-2% of Badin-deposit zeolite containing klinoptilolite and mordenite minerals and preliminarily subjected to heat treatment for 1-2 h at 150-200 C and pressure 0.2-0.6 MPa. EFFECT: decreased number of stages, reduced expenses, and improved quality of product. 1 tbl, 3 ex
