Effect of reactor residence time distribution on polymer functionalization reactions

摘要: Abstract For polymer functionalization reactions, or other types of post-polymerization reactions involving high molecular weight polymers, the extent reaction mers in a particular chain depends on length time that is reactor. Thus, except for plug flow residence distributions (RTD), reactors gives rise to composition distribution (CD) functional groups with breadth proportional RTD. This also true micromixed since polymers behave as segregated elements even when chains are mixed level. In this paper equations derived characterizing group CD 1 3 CFSTRs series which first order mer concentration. When there equal rate constants each reactor can be obtained readily, but more realistic case unequal constants, method integrals delta functions was employed obtain distributions. The methods developed applicable obtaining instances CFSTRs. results showed very strong function conversion. Relatively narrow only limits low conversion, and broadest at conversion about 60%. As expected, narrowing RTD by using tanks narrows CD. series, narrowest same train.
