Title: Hardenable phenol-aldehyde resins and process for preparing them
IPC: C08G2/00
Filed: 1960-01-11
Abstract: A condensation product A of furfural with at least one other aldehyde, which has 2-12 carbon atoms and a CH2 group adjacent to the CHO group, is reacted with a resinous condensation product B from a compound containing an aromatic hydroxyl group, and an aldehyde. Suitable aldehydes for reaction with furfural are:  acetaldehyde, propionaldehyde, butyraldehyde, pentanol, hexanol, crotonaldehyde, and mixtures of acetaldehyde with either a saturated or unsaturated aldehyde containing 3-12 carbon atoms, or with an aromatic aldehyde such as phenyl or naphthyl acetaldehyde, or with both. Reaction is preferably effected under alkaline conditions.  A number of suitable alkaline catalysts are mentioned.  Preferably an excess of furfural is employed. Preferred condensation products B are novolaks or resols prepared from compounds such as phenol, cresol, resorcinol, xylenol, dihydroxydiphenyl methane, dihydroxydiphenyl dimethylmethane, nonyl phenol, allyl phenol, the reaction product of butadiene or of paraffin containing 6 to 20 carbon atoms with phenol on the one hand, and formaldehyde, acetaldehyde, acrolein, crotonaldehyde or furfural on the other.  The products of the invention have good resistance to alkalies, and can be hardened with acid hardening catalysts such as p-toluene sulphonic acid, if desired in admixture with coke powder, synthetic graphite, quartz powder, barium sulphate, silicon carbide, or ferro-silicon as inert fillers.  The hardened products have good mechanical strength and chemical resistance. They are also useful for storing lacquers, especially together with polyvinyl acetals, e.g. polyvinyl butyral which improves the adhesive and elastic properties of the lacquer film.  In the examples, (1) Furyl acrolin is prepared by condensing furfural with acetaldehyde in presence of an aqueous methanol solution of NaOH and heated with a product prepared from phenol and formaldehyde in presence of cyclohexylamine. The products mixed with p-toluene sulphonic acid and coke or quartz powder were mouldable and hardenable; (2) is similar, the phenol-formaldehyde condensation being conducted in two stages-the first with cyclohexylamine as condensation catalyst and the second with p-toluene sulphonic acid; (3) A novolak was condensed with a condensate from furfural, acetaldehyde and butyraldehyde.  Mixed with a solvent, e.g. acetone, methanol, butanol or lauryl alcohol and, if desired a pigment, e.g. TiO2, red iron oxide, silicon carbide, ferro-silicon or graphite, the product yielded a storing lacquer; (4) Furyl acrolin was condensed with a mixture of a two-stage phenol-formaldehyde condensate and a resorcinol-formaldehyde condensate.

Abstract: 918,863. Injection moulding polystyrene. MONSANTO CHEMICAL CO. Jan. 12, 1960 [Jan. 12, 1959], No. 1060/60. Class 87(2). A polystyrene article is moulded by injecting crystallisable polystyrene at a temperature between the second order transition temperature (97C.) and the melting point (230C.) thereof through an orifice into a mould cavity; sufficient crystallinity being developed in the article for it to retain its shape when heated above the second order transition temperature. Crystallisable isotactic or syndiotactic polystyrene prepared by polymerizing styrene with a Ziegler catalyst was extruded at a high temperature (about 250C.) to refine it and reduce its molecular weight, and then quenched. The quenched material was then injected using a cylinder temperature of 190-195C. and a mould heated to 150-170C. The moulding was annealed without distortion by heating to 150C. The graph shows the variation indensity (a measure of crystallinity) as a function of the annealing time at various temperatures; maximum crystallinity being required to improve the rigidity of the moulding. Specification 799,392 is referred to.
