Abstract

Soluble fusible reaction products result from the reaction of (1) a novolac of recurring structural units <PICT:1044149/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 dihalosilane, (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 in the presence of an acid acceptor e.g. a tertiary amine. The products may be cross-linked by heating with an alkali metal or its hydroxide, carbonate, alkoxide or aryloxide or a quaternary ammonium salt as catalyst. 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.
