JT Dickson and Rex Whinfield investigated thermoplastic polyesters in the laboratories of the Calico Printers’ Association Ltd. during the period 1939 to 1941.

Although the aliphatic polyesters prepared by Carothers had proved unrewarding, The aromatic polyesters had remained largely unexplored. By 1939, sufficient evidence had been accumulated favouring the theory that microcrystallinity was essential for the formation of strong synthetic fibres. The need for molecular symmetry in forming microcrystalline polymers was the basis for Whinfield and Dickson’s theoretical approach to the problem, and use of an aromatic based polymer should give a polymer with a sufficiently high melting temperature for synthetic fibre manufacture.
