<p>Azidosulphonylbenzene isocyanaurate cross-linking and foaming agents Cpds. have formula:- (where X is the group where R is halogen or lower alkyl, n is 0, 1 or 2 m is 1 or 2 and n + m does not exceed 3, the azidosulphonyl group being meta or para to the benzene-isocyanurate bond). Specified compounds are tris/metal or para) azidesulphonylbenzene/isocyanurate. They are also photo-resistant and act as stabilisers of polymers against degradation by visible or UV light.</p> |
