LIGHT PETROLEUM POLYMER RESIN PRODUCTION PROCESS |
摘要 |
FIELD: polymer production. SUBSTANCE: polymer resin is prepared via initiated polymerization of unsaturated pyrolysis products with boiling temperature 130- 190 C in amounts 100 wt parts mixed with 25-40 wt parts of styrene and, as additional monomer, 4-6 wt parts of turpentine, initiator being diisopropylbenzene peroxide in amount 1.5-2.0% of the total weight of mixture. Copolymerization is carried out during 24-42 h at 145-150 C followed by distillation of resin and isolation thereof in solid state. EFFECT: reduced coloration of light petroleum polymer resins and increased their yield. 2 tbl, 13 ex
