Abstract

Embodiments include curable compositions including an epoxy resin and a hardener component including a polymer having first constitutional unit, a second constitutional unit, and a third constitutional unit, where the epoxy group to the second constitutional unit has a molar ratio in a range of 0.5:1 to 5:1. Embodiments include prepregs that include a reinforcement component and the curable composition and an electrical laminate formed with the curable composition.

Description

technical field [0001] Embodiments of the present disclosure relate to curable compositions, and in particular to curable compositions comprising polymers and methods of producing the curable compositions. Background technique [0002] A curable composition is a composition comprising a thermally curable monomer capable of crosslinking. Crosslinking (also called curing) converts the curable composition into a crosslinked polymer (ie, cured product) that can be used in various fields, such as in the fields of composites, electrical laminates, and coatings. Some of the properties of curable compositions and crosslinked polymers that may be considered for a particular application include mechanical properties, thermal properties, electrical properties, optical properties, processing properties, and especially physical properties. [0003] For example, glass transition temperature, dielectric constant, and dissipation factor may be properties considered to be very relevant for ...
