(57) A process is disclosed for protecting articles, especially fibres, monofilaments
and films, made from polymers against degradation through exposure to aqueous solutions
containing peroxygen groups, hypochlorite groups or mixtures thereof. The process
comprises coating the articles with a composition capable of protecting the articles
from such solutions. The composition preferably comprises a reactive guanide compound.
The guanide compound is cured in place on the article. The guanide compound is of
the formula:
where n is from 2 to 10, R₁ has from 6 to 15 carbons and is either an alkyl, a cycloalkyl,
a monocyclic aryl, or and alkyl-substituted monocyclic aryl, and R₂ has not more than
15 carbons and is either hydrogen, an alkyl, a cycloalkyl, or a monocyclic aryl or
an alkyl-substituted monocyclic aryl.
