Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
142 words
Moulding composition based on poly(oxymethylene), consisting of (a) from 99.9 to 95 weight percent of a poly(oxymethylene) and (b) from 0.1 to 5 weight percent of a hydroxyphenyl-ureido-s-triazine having the formula ##SPC4## in which R 1 represents a hydrogen atom, an alkyl radical or an alkoxy radical each having from 1 to 6 carbon atoms, a phenyl or a phenoxy radical -- each of which may be substituted by a hydroxyl group or an amino group being able to carry one or two alkyl radicals having from 1 to 6 carbon atoms each -- or an amino group which may carry one or two alkyl radicals having each from 1 to 6 carbon atoms; and R 2 represents a hydrogen atom, a hydroxyl group, an alkyl radical or alkoxy radical each having from 1 to 6 carbon atoms or a phenyl radical.
