Polysulfone-based alloys

Summary of some general assessments concerning chemical behaviour at room temperature of polysulfones and PC, which are not necessarily representative of polysulfone-based alloys or of all grades of polysulfone and PC. These general indications should be verified by consultation with the producer of the selected alloys and by tests under operating conditions.

The often used FPL etdi of an aluminum-lithium alloy bonded with polysulfone leads to interfacial (at the metal oxide/polymer interface) failure (38) which is a surprisingly uncommon type of failure. The results leading to this assignment are shown as XPS C Is and O Is narrow scan spectra in Figure 15. This definitive assignment of failure mode is based on the fact that one failure surfece has an oi gen photopeak similar to the pretreated adherend before bonding and the other failure surfece has an 0 gen photopeak similar to the adhesive. 

The need for an expanding product line led to the development of alloys and composites based on UDEL Polysulfone. Union Carbide introduced a polymer alloy named UCARDEL designed for specific markets in 1971. At about the same time, Uniroyal Inc. introduced an ABS modified UDEL Polysulfone named Arylon T for chrome plated applications requiring higher heat resistance than ABS.
