Thermally stable UV crosslinkable copolyesters: Synthesis, crosslinking and characterisation of poly( 1,4-cyclohexylenedimethylene-1,4-cyclohexane dicarboxylate-co-4,4'-stilbene dicarboxylate)

摘要

Most commercially available oligomers are either liquids or low melting solids, which facilitate photo-crosslinking. There has limited success in controllably including photo-crosslinkable moieties into engineering thermoplastics; in part because many commercial engineering polymers are synthesised at temperatures above 200°C and often further melt processed to form molded products or extruded films at the same temperatures.
