  • ELASTOMERIC POLYMER COMPOSITIONS AND RAIL TRACK STRUCTURES AND SYSTEMS COMPRISING THE SAME
    Publication number: 20240174886
    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.

  • Polyisoidide furanoate thermoplastic polyesters and copolyesters and a use thereof in hot fill packaging
    Patent number: 10125216
    Abstract: Semi-crystalline polyesters from isoidide and 2,5-furandicarboxylic acid are disclosed, as well as semi-crystalline copolyesters from isoidide and a minor amount of either 1,4-butanediol or 2,3-butanediol with 2,5-furandicarboxylic acid, together with processes for making high molecular weight materials by melt polymerization providing a semi-crystalline polymer then performing solid state condensation on the semi-crystalline polymer.
