Abstract

The present invention relates to process of preparing C10, C15 and C20 olefin mixture prepolymer with ethylene cracking C5 fraction. The process includes the Diels-Alder reaction of ethylene cracking C5 fraction containing conjugated diolefin and mono-olefin at temperature of 140-300 deg.c and pressure of 1.0-12.0 MPa for 3-12 hr, cooling before discharging, and subsequent rectifying to eliminate unreacted C5 fraction to obtain C10, C15 and C20 olefin mixture prepolymer. The prepolymer of the present invention may be used in producing C5 petroleum resin with narrow molecular weight distribution, raised compatibility with other hot melt adhesive components SIS, SBS and EVA and extremely expanded use range. In the same time, the present invention raises the utilization rate of polymerisable olefin in C5 fraction effectively.

Description

technical field [0001] The invention belongs to the field of petrochemical industry and relates to a C 5 The method for preparing prepolymer by distillate, particularly relates to a kind of C byproduct of ethylene cracking 5 Fractions prepared containing C 10 、C 15 、C 20 Process for Olefin Hybrid Prepolymers. The thermal polymer obtained by this method can be used to produce C 5 series of petroleum resins, and can also produce C with special application fields 5 petroleum resin. Background technique [0002] With the development of petroleum resin technology, fierce market competition and demand for new products, the raw materials of petroleum resin are developing from "coarse grain" to "fine grain". In order to produce petroleum resin products with high quality and good performance, the composition of raw materials must be strictly controlled. The common method is to control the rectification conditions of raw materials, and add a certain amount of active components ...
