Abstract
1,239,143. Finely divided hardened urea-formaldehyde resins; rubber compositions. CIBAGEIGY A.G. 18 March, 1969 [21 March, 1968], No. 14294/69. Headings C3P and C3R. Cross-linked urea-formaldehyde resins in the form of particles of average diameter below 1000 Š are obtained by adding H 2 N-SO 3 H or a water-soluble ammonium hydrogen sulphate R-NH 3 .HSO 4 , wherein R is H or an organic radical, to an aqueous solution of a ureaformaldehyde precondensate in the presence of a protective colloid, and comminuting, drying and de-agglomerating the resultant gel, the ratio of formaldehyde to urea exceeding 1: 1. Other aminoplast-forming nitrogen compounds, or phenols, may be added to the mixture before or during gel formation. Suitable radicals R include methyl, ethyl, hydroxyethyl, cyclohexyl, and phenyl radicals. Suitable colloids include sodium carboxymethyl-, methyl-, ethyl- and hydroxyethyl-celluloses, polyvinyl alcohol and polymers and copolymers of acrylic and methacrylic acids, in amount of 0À1-10 wt. per cent of the resin. In examples aqueous ureaformaldehyde or urea-melamine-formaldehyde precondensates containing sodium carboxymethyl cellulose or polyvinyl alcohol is mixed at 50-70‹ C. with aqueous sulphamic acid, or sulphamic acid and phenol, or n-butylamine or aniline acid sulphate, or the UF solution is added dropwise to a solution of sulphamic acid and polyvinyl alcohol. The resultant gels are comminuted, washed, dried, and de-agglomerated in a pin-mill, and have bulk densities 50- 218 g/litre, specific surface area 22-302 m<SP>2</SP>/g. and particle size 400-700 Š. A styrene-butadiene rubber composition is prepared containing 50 wt. per cent (relative to the rubber) of such a powder, with other specified conventional additives.
