FIELD: resin industry.
SUBSTANCE: invention relates to production of polyterpenes, which can be used as oiling agent in manufacture of pressure-sensitive glues, in production of solid and liquid oils, etc. Polyterpene are prepared via continuous polymerization of terpene hydrocarbons in presence of zeolite catalyst by feeding starting hydrocarbons into top section of reactor through perforated cartridge, after which monomer vapors move into catalyst-filled reaction zone at a velocity in full reactor cross-section 0.3-0.4 m/s accompanied by continuous dephlegmation of unconverted part of monomer and returning it into reaction zone. Process is carried out for 7-9 h at 160-170°C. Yield of polyterpenes is 72-80%.
EFFECT: increased uniformity of polyterpene composition (98% dimers).
