Reactive polymer resin plasticizer and liquid crystal packaging sealant prepared from same

The invention relates to the technical field of liquid crystal packaging, in particular to a reactive polymer resin plasticizer and a liquid crystal packaging sealant prepared from the reactive polymer resin plasticizer, and the structure of the reactive polymer resin plasticizer is any one of (a), (b) and (c). According to the present invention, the resin plasticizer can achieve the appropriate flexibility through the formula adjustment according to the required glass transition temperature requirement so as to achieve the high bonding strength of the liquid crystal packaging sealant, and the reactive polymer resin plasticizer contains the active group epoxy group or the carbon-carbon double bond, therefore, the resin plasticizer can be cross-linked with main chain resin to form a net to achieve higher cross-linking density, so that the liquid crystal packaging sealant has excellent moisture permeability. 本发明涉及液晶封装技术领域，尤其是一种反应性聚合物树脂增塑剂及其制得的液晶封装密封剂，其中，反应性聚合物树脂增塑剂结构为(a)(b)和(c)中的任一种。该树脂增塑剂能够根据所需的玻璃化转化温度的要求通过配方调
