<p>Disclosed is a method for treating the surface of a strained ring cycloolefin polymer article, in particular an article molded from poly(dicyclopentadiene) or a copolymer of dicyclopentadiene and another strained ring cycloolefin, comprising halogenating the surface of the article with a halogen, a pseudohalogen compound, or an interhalogen compound to improve the properties of the article, by increasing chemical resistance, improving retention of properties upon aging, reducing emission of residual monomer, and encouraging better adhesion of paint.</p> |
