Cresol Novolac/Epoxy Networks: Synthesis, Properties, and Processability
, 2001 Void-free phenolic networks have been prepared by the reaction of phenolic novolac resins with various diepoxides. The stoichiometric ratio can be adjusted to achieve networks with good mechanical properties while maintaining excellent flame retardance.

Reinforcing styrene butadiene rubber with lignin-novolac epoxy resin networks
eXPRESS Polymer Letters, 2015 In this study, lignin-novolac epoxy resin networks were fabricated in the styrene butadiene rubber (SBR) matrix by combination of latex compounding and melt mixing. Firstly, SBR/lignin compounds were co-coagulated by SBR latex and lignin aqueous solution.

Modification of high ortho novolac resin with diacids to improve its mechanical properties
, 2007 To improve the brittleness of high ortho novolac resins, at first, high ortho novolac resins (N) were synthesized and condensation reactions between N and flexible diacids such as adipic acid (DA4) and azelaic acid (DA7) were carried out with different ...
