The effect of chain extender chemical structure on the physical and mechanical
properties of thermoplastic polyurethane/urethaneurea elastomers was systematically
Several series of materials were synthesised using 4,4' -diphenylmethane diisocyanate
(MDI) and poly(tetramethylene oxide) glycol (PTMG), each series incorporating a
particular class of chain extender compound. Elucidation of the influence of chain
extender structural variations within each series was the principal objective of the
A Doctoral Thesis. Submitted in partial fulfilment of the requirements for the award of Doctor of Philosophy of Loughborough University.
