Title: Improvements in or relating to rubber compositions and methods of preserving the same
IPC: C08K5/18
Filed: 1932-03-01
Abstract: Secondary amino derivatives of polyaryl alkanes containing only one amino group in the molecule are used as anti-agers for rubber, and are most readily prepared by condensing a triaryl methyl chloride with a diarylamine, although the primary amine may be prepared first by reacting the triaryl methyl chloride with aniline hydrochloride, the product being then further reacted with a phenol or an amine. Specified compounds are p-phenylaminotetraphenylmethane, tolyl-p-aminotetraphenylmethane, naphthyl-p-aminotetraphenylmethane, p - biphenyl - p - aminotetraphenylmethane, p-phenylaminophenyl-tritolylmethane, p-phenylaminophenyl tribiphenylmethane, biphenylamino-tetrabiphenylmethane, p-phenylaminophenyl-trianisylmethane, p-phenylaminophenyl-trinaphthylmethane, p-naphthylaminophenyl - trinaphthylmethane, p - benzylaminotetraphenylmethane, p - isopropylamino - tetraphenylmethane, p - phenylamino - triphenylmethane, p - naphthylaminotriphenylmethane, biphenylaminotriphenylmethane, phenylaminodiphenylmethane, tolylaminodiphenylmethane, naphthylaminodiphenylmethane, phenylaminodi-biphenylmethane, biphenylamino-di-biphenylmethane, p-phenylamino-1-1-diphenylpropane, p - phenylamino - 1 - 1 - 1 triphenylethane, p-phenylaminodibenzyl.ALSO:The ageing of rubber is retarded by the addition to the mix of a secondary amino derivative of a poly-aryl alkane containing only one amino group in the molecule.  The anti-ager may be used alone or mixed with other age-resisting compounds, before or after vulcanization as it has substantially no accelerating action. Alternatively the anti-ager may be applied to the surface of crude or vulcanized rubber in the form of a powder, paste or solution, or to latex before coagulation.  The anti-agers according to the invention do not discolour light coloured articles, and certain members, e.g. tetra-aryl methane compounds, are used in the "acid cure" because of their inertness to sulphur chloride.  They are most readily prepared by condensing a triaryl methyl chloride with a diarylamine, although the primary amine may be prepared first by reacting the triaryl methyl chloride with aniline hydrochloride, the product being then further reacted with a phenol or amine. Specified compounds are p-phenylaminotetraphenylmethane, tolyl-p-aminotetraphenylmethane, naphthyl-p-aminotetraphenylmethane, p-biphenyl-p-aminotetraphenylmethane, p - phenylamino - phenyltritolylmethane, p-phenylaminophenyltri-biphenylmethane, biphenylaminotetrabiphenylmethane, p-phenylaminophenyltri-anisylmethane, p-phenylaminophenyltrinaphthylmethane, p-naphthylaminophenyltrinaphthylmethane, p-benzylaminotetraphenylmethane, p - isopropylaminotetraphenylmethane, p - phenylaminotriphenylmethane, p - naphthyl - aminotriphenylmethane biphenylaminotriphenylmethane, phenylaminodiphenylmethane tolylaminodiphenylmethane, phenylamino-di-biphenylmethane, biphenylamino-di-biphenylmethane, p-phenylamino 1-1 diphenylpropane, p-phenylamino-1-1-1 triphenylethane, p-phenylaminodibenzyl, &c.
