Paragraph 0018; 0021, (2018/11/22)
The invention discloses a preparation method of a hexafluoropropylene dipolymer. The method comprises the steps that preheated hexafluoropropylene gas is introduced into a reaction container filled with alkyl hexamethylenetetramine fluorine salts show as a formula (IV); continuous reaction is performed under the heating and stirring conditions; reaction products are treated to obtain the hexafluoropropylene dipolymer; in the formula (IV) shown in the description, R is an alkyl group with the carbon number being 1 to 10. The preparation method is used as a novel reaction route; the condition that catalysts and solvents are used for polymerization reaction in a traditional process is avoided; the preparation process is simple; the equipment requirements are low; the reaction conditions are mild.
