Liquid coumarone resin and preparation method thereof

The invention discloses a liquid coumarone resin and a preparation method thereof, and belongs to the field of resin preparation. The preparation method comprises: stirring and mixing a mixture containing indene and coumarone and hydroxy acrylate or hydroxy methacrylate according to a certain ratio, stirring at a temperature of 60-100 DEG C, adding a certain amount of an initiator, and polymerizing the polymerizable components; cooling the polymerized solution, carrying out water washing to remove the initiator, and separating the water; and distilling the washed solution, and removing the unpolymerized compound to obtain the liquid-based coumarone resin. According to the present invention, the obtained liquid coumarone resin has the low softening point, is the liquid at the normal temperature, is not required to be dissolved by adding the organic solvent during the use, and is the environmentally friendly product. 本发明公开了种液体古马隆树脂及其制备方法，属于树脂制备领域。所述液体古马隆树脂的制备包括以下步骤：将含有茚和古马隆的混合物与丙烯酸羟基酯或甲基丙烯酸羟基酯按定比例搅拌混合，在60～100℃下
