Preparation of Azido Polycarbonates via Bulk Polymerization of Halogenated Diols

St‐Charles Jean‐Christophe; Dubois Charles

摘要

Abstract >Azido polymers find use as energetic binders in a variety of composite explosive and propellant applications, but few azido polyesters have previously been reported: a method is introduced for the preparation of two azido polycarbonates, poly(2,2’‐bisazidomethyl‐1,3‐propyl carbonate) and poly(3‐azido‐1,2‐propyl carbonate), possible binder candidates for energetics applications. The preparation method for these polymers involves a two‐step synthesis starting from the bulk polymerization of the commercially sourced diols with diphenyl carbonate in the presence of lanthanum (III) acetylacetonate as a neutral catalyst, and subsequent azidation in cyclohexanone. The physical and thermal characteristics of each are reported, indicating properties similar to other azido‐polymers. The thermal and mechanical properties of cured azido polyester resin mixtures are the subject of ongoing research. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract Type =“Main”XML：Lang =“en”> <标题类型=“main”>抽象</ title> > Azido聚合物在各种复合爆炸物和推进剂应用中使用作为能量粘合剂的用途，但先前已经报道了很少的氮杂多聚酯：介绍了制备两个氮杂聚碳酸酯的方法，聚（2,2'-双唑类甲基 - 1,3-丙基碳酸酯）和聚（3-氮杂-1,2-丙基碳酸酯），可能的粘合剂候选物用于能量应用。这些聚合物的制备方法涉及从在镧（III）乙酰丙酯作为中性催化剂存在下与二苯基碳酸二苯基碳酸二苯基碳酸二苯基碳酸二苯基的块状聚合开始的两步合成，随后在环己酮中刺激。报告各自的物理和热特性，表明与其他氮杂聚合物类似的性质。固化的Azido聚酯树脂混合物的热和力学性能是正在进行的研究的主题。</ p> </摘要> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-29946/'>《Propellants, Explosives, Pyrotechnics》</a> <b style="margin: 0 2px;">|</b><span>2020年第6期</span><b style="margin: 0 2px;">|</b><span>共9页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=St‐Charles Jean‐Christophe&option=202" target="_blank" rel="nofollow">St‐Charles Jean‐Christophe;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Dubois Charles&option=202" target="_blank" rel="nofollow">Dubois Charles;</a> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> <p>école Polytechnique de MontréalChemical Engineering DepartmentMontréal H3T1J4 Canada;</p> <p>école Polytechnique de MontréalChemical Engineering DepartmentMontréal H3T1J4 Canada;</p> </div> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zhdw" style="display: none;">展开▼</span> </div> </div> </li> <li > <span class="lefttit">收录信息</span> <span style="width: 86%;vertical-align: text-top;display: inline-block;"></span> </li> <li> <span class="lefttit">原文格式</span> <span>PDF</span> </li> <li> <span class="lefttit">正文语种</span> <span>eng</span> </li> <li> <span class="lefttit">中图分类</span> <span><a href="https://www.zhangqiaokeyan.com/clc/1837.html" title="爆炸物工业、火柴工业">爆炸物工业、火柴工业;</a></span> </li> <li class="antistop"> <span class="lefttit">关键词</span> <p style="width: 86%;vertical-align: text-top;"> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Energetic polymers&option=203" rel="nofollow">Energetic polymers;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Bulk polymerization&option=203" rel="nofollow">Bulk polymerization;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Azidation reactions&option=203" rel="nofollow">Azidation reactions;</a> </p> <div class="translation"> 机译：精力充沛的聚合物;散装聚合;叠加反应; </div> </li> </ul> </div> </div> <div class="literature cardcommon"> <div class="similarity "> <h3 class="all_title" id="enpatent66">相似文献</h3> <div class="similaritytab clearfix"> <ul> <li class="active" >外文文献</li> <li >中文文献</li> <li >专利</li> </ul> </div> <div class="similarity_details"> <ul > <li> <div> <b>1. </b><a class="enjiyixqcontent" href="/journal-foreign-detail/0704024626190.html">Preparation of Azido Polycarbonates via Bulk Polymerization of Halogenated Diols</a> <b>[J]</b> . <span> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=St‐Charles Jean‐Christophe&option=202" target="_blank" rel="nofollow" class="tuijian_auth tuijian_authcolor">St‐Charles Jean‐Christophe,</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Dubois Charles&option=202" target="_blank" rel="nofollow" class="tuijian_auth tuijian_authcolor">Dubois Charles </a> <a href="/journal-foreign-29946/" target="_blank" rel="nofollow" class="tuijian_authcolor">Propellants, Explosives, Pyrotechnics .</a> <span>2020</span><span>,第6期</span> </span> </div> <p class="zwjiyix translation" style="max-width: initial;height: auto;word-break: break-all;white-space: initial;text-overflow: initial;overflow: initial;"> <span>机译：通过卤代二醇的块状聚合制备氮杂多聚碳酸酯</span> </p> </li> <li> <div> <b>2. </b><a class="enjiyixqcontent" href="/journal-foreign-detail/0704010348886.html">Preparation of aqueous anionic poly(urethane-urea) dispersions.
