| titleOfInvention | Modified novolac resins |
| abstract | Soluble fusible reaction products result from the reaction of (1) a novolac of recurring structural units <FORM:1031909/C3/1> where A is an aromatic hydrocarbon nucleus, R is alkylidene ortho to the OH of both A nuclei to which it is attached, R1 is an alkyl or aromatic hydrocarbon radical para to the OH, and n is 0 or 1; with (2) a diisocyanate; (1) may be obtained by standard novolac procedures from a p-alkyl or p-aryl phenol when n is 1, or from a p-halophenol, followed by replacement of Ha by H when n is 0, and an aldehyde, e.g. formaldehyde, acetaldehyde, butyraldehyde or benzaldehyde. Reaction may be effected in an inert solvent over a wide temperature range. The products may be used in coatings and impregnants for paper, textiles and leather; in paints, varnishes, adhesives and rubber; as moulding compounds with fillers, e.g. wood flour, cotton flock or glass fibres; and when thermoset as binders for sand asbestos, silicon carbide or paper. Specified diisocyanates are toluene-, naphthalene-, 4,4-diphenylmethane-, and C2- 4-alkylene-diisocyanates. The product of the examples is soluble in methylene chloride. |
