Claim 15:
16. A method of bonding a first substrate formed from:
(a) polyaryletherketone;
(b) a polymer containing a phenyl group directly attached to a carbonyl group, optionally wherein the carbonyl group is part of an amide group;
(c) polyphenylene sulfide (PPS); or
(d) polyetherimide (PEI);
to a second substrate comprising the steps of:
(i) exposing the surface of the first substrate to actinic radiation to activate the surface for subsequent bonding wherein the actinic radiation includes radiation with wavelength in the range from about 10 nm to about 1000 nm; and the energy of the actinic radiation to which the surface is exposed is in the range from about 4 J/cm2 to about 300 J/cm2,
(ii) subsequently, bonding the activated surface of the first substrate to the second substrate utilising adhesive.
