Problems solved by technology

[0007] However, most of the optical adhesives currently prepared are used in hard screens, and few optical adhesives meet the elasticity, flexibility and performance required by soft screens. Therefore, it is necessary to develop an acrylate prepolymer. The OCA optical glue prepared by the body can be better suitable for soft screens, and has excellent elasticity, flexibility and performance

[0097] Basic Example 1 A kind of acrylate prepolymer and its preparation method

[0098]

[0099] Wherein, the molar ratio of the alkyl acrylate I to the alkyl acrylate II is 1:10.

[0100] Preparation:

[0101] Add the core acrylate monomer, initiator and chain transfer agent into the solvent, react at 70°C for 0.5h, then add dropwise the alkyl acrylate II and acrylic acid in the shell acrylate monomer, and finally add dropwise acrylamide to derivatize Material, reflux reaction, obtains described prepolymer;

[0102] The initiator is dibenzoyl peroxide, and the initiator accounts for 0.3wt% of the total weight of the core acrylate monomer and the shell acrylate monomer;

Abstract

The invention provides an acrylate prepolymer as well as a preparation method and application thereof, and belongs to the technical field of organic synthesis. The acrylate prepolymer is prepared from the following raw materials: a core acrylate monomer and a shell acrylate monomer; the core acrylate monomer comprises alkyl acrylate I, aryl acrylate and acrylic acid; the shell acrylate monomer comprises alkyl acrylate II, an acrylamide derivative and acrylic acid; the molar ratio of the alkyl acrylate I to the alkyl acrylate II is 1: (9-19). According to the invention, by reasonably controlling the raw material components and proportion of the acrylate prepolymer, the obtained acrylate prepolymer has excellent performance, and the OCA optical cement prepared from the acrylate prepolymer can be better suitable for a soft screen and has excellent elasticity, flexibility and use performance.

Description

technical field [0001] The invention belongs to the technical field of organic synthesis, and in particular relates to an acrylate prepolymer, a preparation method and an application. Background technique [0002] In the photocuring process, the prepolymer is the largest and most important component in the system. It is a low molecular weight polymer resin formed by the initial polymerization of monomers. Prepolymers are generally polymerized from corresponding monomers, and the active groups in the molecules generally do not react completely. The prepolymers have low molecular weight, low viscosity, and certain activity, and can continue to react in the next step. The basic substance of the cured product in the process has a significant impact on the performance of the product after final polymerization. Under specific application conditions, it is necessary to use oligomers with specific properties as the resin matrix. Currently, commonly used polymeric oligomers include ...
