ETHYLENE-VINYL FORMATE COPOLYMERS, PROCESS FOR THEIR PREPARATION, THEIR USE AS FLOW IMPROVERS, AND FUEL AND PROPELLANT COMPOSITIONS COMPRISING THEM |
摘要 |
Copolymer comprising ethylene units and vinyl formate units, the content of free vinyl formate in the polymer preferably being not more than 5000 ppm, based on the weight of the copolymer, a process for its preparation, and its use as flow improver, especially in petroleum distillates, preferably fuel and propellant compositions, especially petroleum middle distillates, and also a fuel and propellant composition comprising a principal quantity of a fuel and propellant and that quantity of a copolymer as above which is effective in improving the flow properties.
