Title: LOW DIELECTRIC CONSTANT POROUS EPOXY-BASED DIELECTRIC
Abstract:
Disclosed herein are compositions comprising an epoxy-functionalized sacrificial polymer, wherein the sacrificial polymer decomposes into one or more gaseous decomposition products at a temperature of 180°C or less for a period of time of 24 hrs or less. Also disclosed are compositions comprising a copolymer derived from an epoxy resin; an epoxy-functionalized sacrificial polymer; and optionally a crosslinker. The epoxy-functionalized sacrificial polymer can be derived from a polycarbonate. Methods of preparing the copolymers described herein are also disclosed. Porous films derived from the copolymers described herein, wherein a majority of the sacrificial polymer in the composition has been degraded to form pores in the porous film are also disclosed.
