Synthesis of silicone-acrylic-modified high-ortho novolac resin with enhanced thermal resistance and surface coating properties

open access: yes, 2021
In the present study, vinyltrimethoxysilane was used to modify high-ortho novolac resin (NR) to obtain a vinyl silicone-modified phenolic oligomer (Si-mod NR). Subsequently, this oligomer is polymerized with methyl methacrylate.

Rheological study of the curing kinetics of epoxy–phenol novolac resin

open access: yesJournal of Applied Polymer Science, 2006
AbstractThe curing reaction of an epoxy–phenolic resin under different conditions was monitored using rheological measurements. The evolution of viscoelastic properties, such as storage modulus, G′, and loss modulus, G″, was recorded. Several experiments were performed to confidently compare the rheological data obtained under varied curing conditions ...
