Abstract
For given nominal molar concentrations in complementary functional groups, the common wisdom is that the reaction rate of those attached to large molecules does not exceed that of small molecule analogues. They are at best equal. The difference in reaction kinetics is more pronounced if reactive molecules are so large that they phase‐separate, which is often so for polymers. In such cases, complementary functional groups from the two phases can meet and react only at the interfaces. Thus, reaction kinetics of functional groups attached to small molecules has always been taken as the upper bound for those attached to polymers. Here we show that under sufficient mixing, reaction kinetics of two immiscible reactive polymers can be significantly higher than that of small molecule analogues. This phenomenon is attributed to the combined effects of increasing collision probability originated from mixing‐induced interfacial area generation, longer relaxation time of reactive polymer chains, and eventually interfacial slip. © 2004 American Institute of Chemical Engineers AIChE J, 50:2604–2612, 2004

molar concentrations in complementary functional groups, the common wisdom is that the reaction rate of those attached to large molecules does not exceed that of small molecule analogues. They are at best equal. The difference in reaction kinetics is more pronounced if reactive molecules are so large that they phase‐separate, which is often so for polymers. In such cases, complementary functional groups from the two phases can meet and react only at the interfaces. Thus, reaction kinetics of functional groups attached to small molecules has always been taken as the upper bound for those attached to polymers. Here we show that under sufficient mixing, reaction kinetics of two immiscible reactive polymers can be significantly higher than that of small molecule analogues. This phenomenon is attributed to the combined effects of increasing collision probability originated from mixing‐induced interfacial area generation, longer relaxation time of reactive polymer chains, and eventually interfacial slip. © 2004 American Institute of Chemical Engineers AIChE J, 50:2604–2612, 2004</p></abstract></abstractGroup></contentMeta></header></component></istex:document></istex:metadataXml><mods version="3.6"><titleInfo lang="en"><title>Reaction kinetics of multiphase polymer systems under flow</title></titleInfo><titleInfo type="alternative" contentType="CDATA" lang="en"><title>Reaction kinetics of multiphase polymer systems under flow</title></titleInfo><name type="personal"><namePart type="given">Lian‐Fang</namePart><namePart type="family">Feng</namePart><affiliation>State Key Laboratory of Polymer Reaction Engineering, College of Materials Science and Chemical Engineering, Zhejiang University, Hangzhou, China</affiliation><affiliation>Laboratory of Chemical Engineering Sciences, CNRS‐ENSIC‐INPL, Nancy, France</affiliation><role><roleTerm type="text">author</roleTerm></role></name><name type="personal"><namePart type="given">Guo‐Hua</namePart><namePart type="family">Hu</namePart><affiliation>Laboratory of Chemical Engineering Sciences, CNRS‐ENSIC‐INPL, BP 451, 54001 Nancy, France</affiliation><affiliation>E-mail: hu@ensic.inpl‐nancy.fr</affiliation><affiliation>Correspondence address: Laboratory of Chemical Engineering Sciences, CNRS‐ENSIC‐INPL, BP 451, 54001 Nancy, France</affiliation><role><roleTerm type="text">author</roleTerm></role></name><typeOfResource>text</typeOfResource><genre type="article" displayLabel="article" authority="ISTEX" authorityURI="https://content-type.data.istex.fr" valueURI="https://content-type.data.istex.fr/ark:/67375/XTP-6N5SZHKN-D">article</genre><originInfo><publisher>American Institute of Chemical Engineers</publisher><place><placeTerm type="text">New York</placeTerm></place><dateIssued encoding="w3cdtf">2004-10</dateIssued><dateCaptured encoding="w3cdtf">2003-07-28</dateCaptured><copyrightDate encoding="w3cdtf">2004</copyrightDate></originInfo><language><languageTerm type="code" authority="rfc3066">en</languageTerm><languageTerm type="code" authority="iso639-2b">eng</languageTerm></language><physicalDescription><extent unit="figures">9</extent><extent unit="tables">0</extent><extent unit="references">30</extent><extent unit="words">6801</extent></physicalDescription><abstract lang="en">For given nominal molar concentrations in complementary functional groups, the common wisdom is that the reaction rate of those attached to large molecules does not exceed that of small molecule analogues.
