Poly(ether ether ketone), PEEK, is known for its high thermal stability, chemical and corrosion resistance, and versatility. When functional groups are introduced to PEEK, crystallinity is often disrupted causing some of the desirable properties to diminish. Synthetic routes that allow functionalization, but permit the crystallinity to be maintained are highly desirable. This presentation will focus on our attempts to prepare functional, semi-crystalline PEEK analogues. The overall project has two goals: 1) to demonstrate semi-crystalline properties in copolymers of PEEK with pendent functionalization sites, and 2) to synthesize copolymers of PEEK with pendent functional groups. The optimum percentage of traditional PEEK in the copolymers was investigated, as was the importance of the monomer addition order. The level of crystallinity was determined via DSC and X-ray diffraction analyses. Copolymers of PEEK containing up to 25 % of repeat units derived from 3,5-difluorobenzophenone remain semi-crystalline, but with better solubility than PEEK.
