Abstract

The present invention relates to elastomeric polymer compositions comprising an acrylate and the reaction product of an acetoacetylating agent and a polyol. In particular, such elastomeric polymer compositions can be used in railway track structures. The invention also relates to a method for applying the elastomeric polymer composition in railway track structures, in particular, the method of applying the polymer composition may advantageously utilise a C-Michael addition reaction which is facilitated by the reaction product of an acetoacetylating agent and a polyol present in the polymer. The invention further relates to railway track structures and systems comprising the elastomeric polymer compositions.
