FLAME RETARDANT AND INTUMESCENT COMPOUND

摘要

The invention relates to a method of rendering solid matter flame-resistant. The method comprises applying to the solid matter a poly(arylalkyl ketone) or the composition comprising the same. The poly(arylalkyl ketone) has monomer units of the general formula [-ar-(CX2)n-C(O)-]. ar is an aromatic, arylaliphatic or arylalicyclic moiety with a main chain of 5 to about 36 carbon atoms and 0 to 2 heteroatoms. X is selected from a group of substituents so that the group -(CX2)n- is an electron donating group providing electron density to the moiety ar. nis 1 or 2.
