Abstract Polyether telechelics based on ethylene glycol,1,2-propylene glycol and 1,4- butylene glycol of
with various molar masses and bearing at both terminals functional groups such as maleimide,
itaconimide, nadimide and hydroxyl groups were individually examined as toughening agents for
an unsaturated polyester resin (UPER). For a given telechelic, the toughening effect was evaluated
at different mass ratios. The difference in toughening efficacy arose from the differential reactivity
of the telechelics end groups combined with the unsaturation of the UPER with the reactive
diluent, styrene. This causes a differential distribution of the polyether groups in the UPER
matrices, resulting in a differential… More >
