Patent number: 5194563Abstract: 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.Type: GrantFiled: April 2, 1991Date of Patent: March 16, 1993Inventor: Allan S. Hay

Patent number: 5182357Abstract: One hundred percent thermosetting phenol/formaldehyde (P/F) resin and method of preparation thereof are disclosed. The resin comprises a molar ratio of F/P of about 1.2-1.7, has a softening point of about 80.degree. C. and cures at temperature of about 140.degree.-160.degree. C. The method comprises heating the reactants in a solvent-less system in the presence of an ortho directing catalyst while monitoring the amount of free formaldehyde present in the reaction system.Type: GrantFiled: October 22, 1991Date of Patent: January 26, 1993Assignee: DAP, Inc.Inventor: Gary L. Linden
