Abstract

The invention relates to a method for preparing a prepolymer containing C10, C15, and C20 olefins by using ethylene cracking C5 fractions as raw materials. , carry out Diels-Alder reaction at a pressure of 1.0-12.0 MPa for 3-12 hours, then cool down and discharge the material, and rectify to remove unreacted C5 components to obtain a prepolymer containing a mixture of C10, C15, and C20 olefins. The C5 petroleum resin produced by the prepolymer prepared by the method of the present invention has a narrow molecular weight distribution, can improve the compatibility of the resin with other hot-melt adhesive substrates SIS, SBS, EVA, greatly expands the scope of use of the petroleum resin, and can It is widely used in adhesives, coatings, inks, asphalt, rubber tires and other fields; at the same time, it can effectively improve the utilization rate of polymerizable olefins in C5 fractions.

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 ...
