Modeling of High‐Pressure Ethene Homo‐?and?Copolymerization

Peikert Paul; Pflug Kristina M.; Busch Markus

摘要

Abstract >While reaction engineering of low‐molecular weight compounds mainly focuses on equilibria and selectivities, polymer properties are tremendously influenced by molecular weight distribution as well as branching structure. In order to determine the branching structure of low‐density polyethylene (LDPE) copolymers in dependence on chosen process conditions, a Monte‐Carlo approach was developed. By modeling the topology as well as the comonomer distribution in the polymer chains a deeper insight in the process‐microstructure‐properties relationship is gained. </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> 虽然低分子量化合物的反应工程主要侧重于平衡和选择性，但聚合物性质受到分子量分布的巨大影响以及分支结构。为了确定低密度聚乙烯（LDPE）共聚物的支化结构，依赖于所选择的工艺条件，开发了蒙特卡罗方法。通过建模拓扑以及聚合物链中的共聚单体分布，获得了过程 - 微观结构的更深层次的洞察力。</ 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-16114/'>《Chemie-Ingenieur-Technik: Verfahrenstechnik Technische Chemie Apparatewesen Biotechnologie》</a> <b style="margin: 0 2px;">|</b><span>2019年第5期</span><b style="margin: 0 2px;">|</b><span>共5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=Peikert Paul&option=202" target="_blank" rel="nofollow">Peikert Paul;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Pflug Kristina M.&option=202" target="_blank" rel="nofollow">Pflug Kristina M.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Busch Markus&option=202" target="_blank" rel="nofollow">Busch Markus;</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>Ernst-Berl InstitutTU Darmstadt Fachbereich ChemieAlarich-Weiss Stra?e 8 64287 Darmstadt Germany;</p> <p>Ernst-Berl InstitutTU Darmstadt Fachbereich ChemieAlarich-Weiss Stra?e 8 64287 Darmstadt Germany;</p> <p>Ernst-Berl InstitutTU Darmstadt Fachbereich ChemieAlarich-Weiss Stra?e 8 64287 Darmstadt Germany;</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/238.html" title="化学工业">化学工业;</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=Polymerization&option=203" rel="nofollow">Polymerization;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=High pressure&option=203" rel="nofollow">High pressure;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=LDPE process&option=203" rel="nofollow">LDPE process;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Modeling&option=203" rel="nofollow">Modeling;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Monte‐Carlo&option=203" rel="nofollow">Monte‐Carlo;</a> </p> <div class="translation"> 机译：聚合;高压;LDPE过程;建模;蒙特卡洛;
