Isocyanurate compounds or resins have the structure (I) in which Y is an hydroxyl group —OH or a maleimide group Formula (II) provided that at least one maleimide group is present, and Q is any divalent organic moiety, aliphatic or aromatic.
摘要:
A linear or cyclic siloxane compound contains pendant carbon to carbon double bonds, Si—H bonds, and pendant oxetane functionality. These compounds have two curing temperatures, one associated with a hydrosilation reaction between the carbon to carbon double bond and the Si—H entity, and the other associated with the ring opening of the oxetane.

A conductive resin composition containing a curable resin, such as an adhesive resin, and a conductive metal filler, has improved conductivity through the addition of a metal salt of a carboxylic acid to the composition.
摘要:
An assembly of a semiconductor die attached to a substrate is made with a composition comprising compounds that contain an oxazoline functionality and an electron acceptor or an electron donor functionality. Electron donor functionalities include styrenic, cinnamyl, and vinyl ether groups. Electron acceptor functionalities include maleimide, acrylate, fumarate, and maleate groups. An exemplary compound has the structure: formula (I).
