Problems solved by technology

The bile acid derivatives in JP-P-11-279118 only have a single acrylic acid functional group, if combined with other acrylic acid, the physical properties of the composition such as glass transition temperature or thermal conductivity will be affected if the degree of crosslinking is insufficient
In addition, in the bile acid derivatives in the two papers, the molecular chain between the acrylic functional group and the polyalicyclic core is short, and after hardening, it will be too hard and brittle, which is not suitable for applications such as electronic devices or packaging materials.

Abstract

The invention provides a polyalcyl acrylate, which can be further mixed with a photo and / or a thermal initiator or other acrylates to form an acrylate composition. The inventive acrylate composition has high glass transition temperature and high heat-conducting property after curing. Therefore, the composition can be used as optical devices, photoelectric devices, electronic devices, coatings, printing ink or binders.

Description

Technical field [0001] The present invention relates to an acrylate composition, and more particularly to the polyalicyclic acrylate contained therein. Background technique [0002] The application range of acrylate (commonly known as acrylic) is quite wide. Taking the current information society as an example, electronic / optical / optical devices need to be processed through acrylate processing. In addition to the above applications, acrylates are also used in printing inks, coatings, adhesives and other fields, which have a significant impact on modern life. With the rapid development of science and technology, how to develop new products with high functions and high added value is the common goal of all industries. In the future, more new materials and new fields using acrylate should be continuously developed. [0003] Currently, LED materials as solid-state light sources have the following requirements: (1) Packaging materials with optical properties such as high light transmi...
