The addition of fillers to a polymer changes the melt rheological behavior of the polymer. A knowledge of the viscosity vs. shear-rate flow curves of the filled system at various temperatures and as a function of filler parameters (such as filler type, shape, and amount) is necessary for process design, optimization, and trouble shooting. The generation of such rheological data is ezpensive and cumbersome in view of the broad range of fillers and the large numbers of filler parameters. In the present article, a unifying approach is proposed that coalesces the flow curves of filled systems of a polymer at various temperatures into a master curve that is independent of the filler parameters. An effective methods is presented to estimate the rheograms of filled systems with the use of a master curve, characteristic of a genetic resin type, knowing the melt-flow index and glass-transition temperature of the system. Master curves have been reported for filled system of low-density polyethylene, high-density polyethylene, poly-propylene polystyrene, nylons, poly(ethylene terephthalate), and polycarbonate.", "publicationTitle": "Polymer Composites", "publisher": "", "place": "", "date": "01/1983", "volume": "4", "issue": "1", "section": "", "partNumber": "", "partTitle": "", "pages": "53-63", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.1002/pc.750040109", "citationKey": "", "url": "http://doi.wiley.com/10.1002/pc.750040109", "accessDate": "2014-10-15T23:09:03Z", "PMID": "", "PMCID": "", "ISSN": "0272-8397, 1548-0569", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "en", "libraryCatalog": "CrossRef", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "calcium carbonate" }, { "tag": "filled polymers" }, { "tag": "glass fibers" }, { "tag": "high density polyethylene" }, { "tag": "low density polyethylene" }, { "tag": "master curves" }, { "tag": "melt flow index" }, { "tag": "mica" }, { "tag": "optimization" }, { "tag": "polymer rheology" }, { "tag": "polypropylenes" }, { "tag": "process design" }, { "tag": "rheograms" }, { "tag": "rheological properties" }, { "tag": "rheology" }, { "tag": "shear rate" }, { "tag": "talc" }, { "tag": "troubleshooting" }, { "tag": "unified curves" }, { "tag": "viscosity" } ], "collections": [], "relations": {}, "dateAdded": "2014-11-02T13:12:44Z", "dateModified": "2014-11-02T13:12:44Z" } }, { "key": "WXWEUPVV", "version": 6, "library": { "type": "group", "id": 300747, "name": "MELT FLOW INDEX", "links": { "alternate": { "href": "https://www.zotero.org/groups/melt_flow_index", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/300747/items/WXWEUPVV", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/melt_flow_index/items/WXWEUPVV", "type": "text/html" } }, "meta": { "createdByUser": { "id": 2129275, "username": "draroonshenoy", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/draroonshenoy", "type": "text/html" } } }, "creatorSummary": "Shenoy et al.", "parsedDate": "1982", "numChildren": 0 }, "data": { "key": "WXWEUPVV", "version": 6, "itemType": "journalArticle", "title": "Rheograms of cellulosic polymers from the melt flow index", "creators": [ { "creatorType": "author", "firstName": "A.

Melt flow index is shown to be useful in depicting the temperature dependence of copolymer melts and in estimation of their flow activation energy. The three copolymer systems included are styrene-butadiene-styrene (SBS), ethyl vinyl acetate (EVA) and a liquid crystalline copolyester based on hydroxybenzoic acid-polyethylene terephthalate (HBA-PET) respectively. The observed behaviour indicates a significant degree of retention of physical network structure below the cross-over point in a MFI-temperature−1 plot", "publicationTitle": "Materials Chemistry and Physics", "publisher": "", "place": "", "date": "3/1988", "volume": "19", "issue": "1-2", "section": "", "partNumber": "", "partTitle": "", "pages": "123-130", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.1016/0254-0584(88)90005-3", "citationKey": "", "url": "http://linkinghub.elsevier.com/retrieve/pii/0254058488900053", "accessDate": "2014-10-17T15:30:04Z", "PMID": "", "PMCID": "", "ISSN": "02540584", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "en", "libraryCatalog": "CrossRef", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "activation energy" }, { "tag": "block copolymers" }, { "tag": "copolymer melts" }, { "tag": "melt flow index" } ], "collections": [], "relations": {}, "dateAdded": "2014-11-02T12:31:14Z", "dateModified": "2014-11-02T12:31:14Z" } } ]
