Abstract (en)
[origin: WO8604075A1] Epoxy novolac resins having reduced 2-functional components and a process for reducing 2-functional components in novolac resin which may be used to prepare the epoxy novolac resins. When 2-functional and 3-functional components are present in an epoxy phenol-formaldehyde novolac resin, the weight ratio of the 2-functional component to the 3-functional component is less than 1.1:1. When 2-functional and 3-functional components are present in an epoxy cresol-formaldehyde novolac resin, the weight ratio of the 2-functional component to the 3-functional component is less than 0.5:1. The epoxy novolac resins of this invention when cured exhibit increased glass transition temperature. These resins are useful in the preparation of composites, molding, castings, coating, adhesives and laminates.
