| 摘要 |
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: <CHEM> 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. |
