A polymer composition comprises (1) an olefinic polymer having hydroxyl- or carboxyl-reactive groups, for example an epoxy group, an alkylolated amide group, or an isocyanate group which may be blocked if required, and (2) a flexibilising cross-linking agent comprising a lactone polyester chain compound, for example polycaprolactone, bearing at least two carboxyl or hydroxyl groups. The composition may be cross-linked to give flexible tough coatings. |
