Abstract

The invention provides a double-terminal amino active ester and a preparation method thereof, and a thermosetting resin composition. The double-terminal amino active ester has a structure representedby a structural formula (I), wherein the main chain structure of the double-terminal amino active ester has aryl ester groups and aromatic amino functional groups at the same time. According to the invention, by using the double-terminal amino active ester as a curing agent for an epoxy resin, the thermosetting resin composition of the double-terminal amino active ester has a low dielectric constant, a low dielectric loss factor, good heat resistance and toughness and excellent bonding force with metal.

Description

technical field [0001] The present invention relates to a kind of double-terminated amino active ester useful as a component of a thermosetting resin composition, a preparation method of the double-terminated amino active ester, a thermosetting resin composition and its application, especially a kind of aromatic The active ester of ester group and aromatic amino functional group and its thermosetting resin composition, as well as cured products, semiconductor sealing materials, prepregs, circuit substrates and laminated films made of the thermosetting resin composition. Background technique [0002] In recent years, with the development of electronic information technology, miniaturization and high density of electronic equipment installation, large capacity and high frequency of information, more and more requirements have been put forward for the dielectric properties, water absorption and heat resistance of electronic materials. high demands. [0003] The material prepar...
