Thermal and spectroscopic data suggest a blocky structure of the copolymer prepared. Nuclear magnetic resonance spectroscopy shows an average degree of polymerization of the hard segments of about 6. By heating in the presence or absence of a catalyst, the monoacetylene units in the hard segments are cross\u2010polymerized below and above their melting temperature. The crosspolymerized material reveals a maximum gel fraction of 93,5 wt.\u2010%, does not crystallize and shows reversible deformability in contrast to the starting polymer. In accordance with previous reports it is concluded that cross\u2010polymerization is possible only in a polymer distinguished by some degree of chain ordering.<\/jats:p>","DOI":"10.1002\/macp.1995.021960517","type":"journal-article","created":{"date-parts":[[2003,4,17]],"date-time":"2003-04-17T10:04:30Z","timestamp":1050573870000},"page":"1593-1606","source":"Crossref","is-referenced-by-count":2,"title":["A triple\u2010bonds\u2010containing poly(ether\/ester): synthesis, characterization and cross\u2010polymerization"],"prefix":"10.1002","volume":"196","author":[{"given":"Zlatan","family":"Denchev","sequence":"first","affiliation":[]},{"given":"Ivo","family":"Dudevski","sequence":"additional","affiliation":[]},{"given":"Jordanka","family":"Petrova","sequence":"additional","affiliation":[]},{"given":"Stoyko","family":"Fakirov","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2003,3,12]]},"reference":[{"key":"e_1_2_1_1_2","doi-asserted-by":"publisher","DOI":"10.1021\/ma00230a005"},{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja00363a061"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1295\/polymj.11.813"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1002\/pol.1969.150070315"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1002\/pol.1982.170200413"},{"key":"e_1_2_1_6_2","doi-asserted-by":"crossref","first-page":"824","DOI":"10.1515\/znb-1969-0708","volume":"24","author":"Wegner G.","year":"1969","journal-title":"Z.
