Novolacs from paraformaldehyde

Journal of Applied Polymer Science, 1979
AbstractNovolacs were prepared from phenol, paraformaldehyde, and variable amounts of water and methanol using oxalic acid as a catalyst. The retarding effect of water and methanol is clearly shown. Diffusion of reactants in the two‐phase system does not seem to have a bearing on the measurements of reaction kinetics.

Structural analysis of novolacs

Journal of Polymer Science, 1955
AbstractThe structure of certain novolacs, prepared by polycondensation of formaldehyde with phenol, p‐cresol, and m‐cresol respectively, was investigated. The novolacs were transformed into saturated hydrocarbons, thus expelling the oxygen, by a relatively mild high pressure hydrogenation (300°C., 250 atm.) using 100% by weight of a nickelcopper on ...

Novolac-based resists

Advanced Materials for Optics and Electronics, 1994
AbstractThe performance of novolac–diazonaphthoquinone‐based positive‐working resists is discussed in terms of the molecular weight distributions and microstructures of the novolac resins and the structural variations in the photoactive dissolution inhibitor.

Inorganic esters of novolacs

Journal of Polymer Science Part A-1: Polymer Chemistry, 1968
AbstractReaction of conventional novolacs with polyfunctional materials is known to yield crosslinked infusible products. Surprisingly, high proportions of polyfunctional phosphorus derivatives can be esterfied with o,o′‐linked novolacs without encountering gelation.
