Title: Improvements in or relating to resinous compositions comprising a glycidyl polyetherand a phenol-formaldehyde resin
Inventor: NARRACOTT ERIC SYLVESTER
IPC: C08L63/00
Filed: 1953-09-03
Abstract: A curable composition consists of a phenolformaldehyde novolac resin mixed with a glycidyl ether of a polyhydric phenol or alcohol.  The compositions are curable with hexamethylene tetramine which provides the methylene groups necessary for curing the novolac and ammonia for curing the glycidyl ether.  The curing time of the novolac is shortened by the glycidyl ether.  The two resins may be mixed as powdered solids or a liquid glycidyl ether may be added during preparation of the novolac.  The mixtures may be used, with conventional fillers, e.g. woodflour, paper, cotton, mica, asbestos, sand or abrasive material for moulding or, in solution, as binding agents or adhesives.  Examples describe the use of novolac resins from phenol, formaldehyde and oxalic acid, glycidyl ethers of 2,2-bis-(4-hydroxyphenyl) propane being added either during manufacture of the novolac or to the molten novolac. Curing was effected with hexamethylene tetramine.  In two of the examples, a liquid polyglycidyl ether of glycerol was employed instead of the glycidyl ether of a phenol.  Specifications 681,001, 681,991 and 690,997, [Group XX], are referred to.
