Polymer composition and method of making the same
摘要:
A novel novolac prepared by acid catalyzed condensation between biphenols or bisphenofluorenes and fluorenone is presented. The polymers exhibit excellent oxidative thermal stability and high carbon content, suitable for dielectric, etch stop applications as spin-on material.
