Prolonged thermal treatment at 290\u00b0C gives rise to a copolymer that no longer reveals melting or crystallization. In accordance with previous reports, this effect is attributed to the formation of a random copolymer. Additional annealing of such samples at the relatively low temperature of 140\u00b0C results in the reappearance of melting endotherms in the differential scanning calorimetry curves. This effect is explained by crystallization\u2010induced sequential reordering from random to block copolymer by means of transreactions. In that way a PBT\/PAr blend was shown to be another polymer system, along with poly(ethylene terephthalate) (PET)\/polycarbonate (PC) and PET\/PAr blends, in which the entire cycle is realized, from two homopolymers via a block\u2010 and random copolymer to a block copolymer. The unusually low temperature at which the crystallization\u2010induced sequential reordering to block polymers takes place is explained by the miscibility of PBT and PAr which enables transreactions to take place in the bulk.<\/jats:p>","DOI":"10.1002\/macp.1996.021970922","type":"journal-article","created":{"date-parts":[[2003,4,17]],"date-time":"2003-04-17T10:06:42Z","timestamp":1050574002000},"page":"2869-2887","source":"Crossref","is-referenced-by-count":28,"title":["Sequential reordering in condensation copolymers, 2.
