{"title":"Bimodal Molecular Weight Distribution Formed in Emulsion Polymerization with Long‐Chain Branching","authors":"H. Tobita","doi":"10.1081/PRE-120026377","DOIUrl":"https://doi.org/10.1081/PRE-120026377","url":null,"abstract":"It is known that the molecular weight distribution (MWD) formed in emulsion polymerization of ethylene can be bimodal. A simplified model is used to investigate the emulsion polymerization that involves chain transfer to polymer, aiming at finding necessary conditions to form a bimodal MWD. According to the present theoretical investigation, a bimodal MWD can be formed when the probability that the primary chain end is connected to a backbone chain, P b is larger than 0.5. The bimodality for these cases results from the limited volume effect, that is, the high molecular weight profiles are distorted by the small particle size, which is comparable to the size of the largest branched polymer molecule formed in a particle. During Interval II, the P b ‐value could be approximately equal to C p x c /[C p x c +C m (1 −x c )] in usual emulsion polymerization without using the chain transfer agents, where C p and C m are transfer constants to polymer and to monomer, respectively, and x c is the conversion at which Interval II ends, and therefore, one can predict the possibility of obtaining a bimodal MWD on the basis of these reaction parameters. On the other hand, if the experimentally obtained MWDs are bimodal even when P b < 0.5, the origin of bimodality would be attributed to other reaction mechanisms, such as the chain‐length dependent branching reactions and combination of two different MWDs formed in large and small polymer particles.","PeriodicalId":124648,"journal":{"name":"Polymer Reaction Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126064414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Reaction time was also varied from 10–110 min to explore effect of particle size of PET and reaction time on batch reactor performance. Particle size of PET and reaction time required were optimized. Disodium terephthalate (TPA salt) and ethylene glycol (EG) remain in liquid phase. EG was recovered by salting‐out technique. Disodium terephthalate was separated by acidification to obtain solid terephthalic acid (TPA). Produced TPA and EG were analyzed qualitatively and quantitatively. Yields of TPA and EG were almost equal to PET conversion. Depolymerization reaction rate was first order to PET concentration as well as first order to sodium hydroxide concentration. Acid value of TPA changes with reaction time. This indicates that PET molecule gets fragmented and hydrolyzes simultaneously with aqueous sodium hydroxide to produce EG and disodium terephthalate. Thermodynamics was also undertaken by determination of activation energy, Arrhenius constant, equilibrium constant, Gibbs free energy, enthalpy and entropy. Dependence of hydrolysis rate constant on reaction temperature was correlated by Arrhenius plot, which shows activation energy of 26.3 kJ/mol and Arrhenius constant of 427.2 L/min/cm2.","PeriodicalId":124648,"journal":{"name":"Polymer Reaction Engineering","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123328369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
