Vinyl resin for high-frequency and high-speed CCL and preparation method thereof

The invention discloses vinyl resin for high-frequency and high-speed CCL and a preparation method of the vinyl resin. The preparation method comprises the following steps: adding a divinyl monomer, a monovinyl monomer and an initiator into a solvent, and carrying out anionic polymerization to obtain a copolymer solution; and washing and concentrating the copolymer solution to obtain the vinyl resin for the high-frequency and high-speed CCL. According to the preparation method, anionic polymerization is adopted, the polymer chain segment distribution coefficient is narrow, and impurity factors cannot be introduced into the polymer. The vinyl resin has a low-polarity chemical structure, excellent high heat resistance and electrochemical performance, relatively high peel strength and relatively low dielectric constant and dielectric loss. 本发明公开了一种高频高速CCL用乙烯基树脂及其制备方法；该制备方法包括如下步骤：在溶剂中加入二乙烯基单体、单乙烯基单体以及引发剂进行阴离子聚合，得到共聚物溶液；对共聚物溶液进行水洗、浓缩后，得到该高频高速CCL用乙烯基树脂。该制备方法采用阴离子聚合，其中的聚合物链段分布系数窄，且不会对聚合物引入杂质因子。该乙烯基树脂具有低极性的化学结构以及优异的高
