    专利说明:


    This invention relates to compositions of medium and heavy oil distillates with good flow and filterability properties.
    The purpose of the invention is to improve the low-temperature properties of the composition by improving its flowability and filterability at low temperatures.
    Preparation of ethylene copolymers
    Various ethylene copolymers are obtained by using for this purpose a continuous reaction tank operating at high pressure by copolymerizing ethylene and each comonomer at each temperature and pressure given in table. 1, and the process takes place in the presence of tert-butyl-.
    f
    peroxybenzoate as a substance that initiates polymerization, and propane as a reagent that provides chain transfer.
    The concentrations of comonomers and the numerical values of the average molecular weight of ethylene copolymers obtained in the course of the experiments are given in Table. 2
