He, Z. and Mitchell, G.R. (1994) Crystallization of random aromatic copolyesters containing flexible spacer chains and side-groups. Polymer, 35 (6). pp. 1322-1325. ISSN 0032-3861 doi: 10.1016/0032-3861(94)90031-0
Abstract/Summary
The crystallization behaviour of a series of random copolymers of varying chemical composition is reported. For polymers containing a high proportion of alternating rigid aromatic units and flexible spacers, conventional liquid crystalline and crystalline phase behaviour is observed. The introduction of a substantial fraction of a second shorter rigid unit containing side-chains leads to a broad endotherm in the d.s.c. scan covering some 150°C. Subsequent isothermal crystallization at any point within the broad endotherm leads to the generation of sharp endotherms at temperatures just above the recrystallization temperature. We attribute this behaviour to the crystallization of clusters of molecules containing similar random sequences. Such crystals are non-periodic along the chain direction.
