    Abstract: An improved resin for use in making honeycomb sandwich panels. The improvement involves modifying a phenolic resin so that the amount of smoke and heat generated during combustion is reduced. The reduction in smoke and heat generation is achieved by reducing the amount of phenol used to form the phenolic resin. The phenol is replaced by low-smoke producing sulfone compounds such as 4,4′-bisphenol-S, 3,3′-bisphenol-S, biphenol and bisphenol ethers which reduce the number of smoke producing methylene or methylene ether linkages present in the cured phenolic resin. The low-smoke producing resin may be used as a dip resin for coating the honeycomb or as the matrix resin for the core and face sheets of the sandwich panel.

  • Patent number: 5194563
    Abstract: Linear aromatic polymeric species, particularly oligomers and polymers are produced under mild conditions in good yield by reacting an at least binuclear aromatic compound with an alkylidene bisphenol in the presence of a non C-alkylatable hydroxy substituted aromatic compound effective to stabilize a generated carbonium ion intermediate; the alkylidene bisphenol may be formed in situ from a ketone or aldehyde in the presence of a catalytic amount of a hydroxy substituted aromatic compound effective to generate a carbonium ion with the ketone or aldehyde; carrying out the reaction under reduced pressure, particularly high vacuum permits direct production of high polymers; the oligomers are useful in the manufacture of high molecular weight engineering or industrial plastics; the polymers may be used directly as such plastics.
