4,4 - -bisphenol Novolac, molecular weight

Dependence of 4,4 -(l-Methylethylidene)bisphenol Novolac Molecular Weight on the mole ratio of Methanal to Aromatic monomer (data from ref [33])... [Pg.631]

The three most often used epoxy resins for monolithic surfacings are the bisphe-nol A, bisphenol F (epoxy novolac), and epoxy phenol novolac. These base components are reacted with epichlorhydrin to form resins of varying viscosity and molecular weight. The hardening system employed to effect the cure or solidification will determine the following properties of the cured system ... [Pg.414]

Diglycidyl ethers of bisphenol A (DGEBA or Bis A epoxies) Diglycidyl ethers of bisphenol F (DGEBF or Bis F epoxies) -low-molecular-weight epoxy coatings Epoxy phenol or cresol novolac multifunctional resins... [Pg.13]

The diglycidylether of Bisphenol A (DGEBA) is where n = 0. With increasing n, the viscosity of the epoxy resin increased imtil it becomes a solid epoxy. At high molecular weight, the structure is basically the polyhydroxyether of Bisphenol A termed Phenoxy (PHE). Epoxidized novolacs (phenol-formaldehyde resins) are also employed in epoxy thermosetting systems. Epoxies are typically crosslinked with di- (or higher) amines (either aliphatic or aromatic). [Pg.187]
