Decahydronaphthalene, 1,2,3,4\u2010tetrahydronaphthalene, 1,3,5\u2010trimethylbenzene, tetrachloroethylene, xylene and <jats:italic>p<\/jats:italic>\u2010xylene were used as mobile phases. While <jats:styled-content style=\"fixed-case\">PE<\/jats:styled-content> is adsorbed to various extents on all the tested carbonaceous sorbents from the majority of the solvents, <jats:styled-content style=\"fixed-case\">PP<\/jats:styled-content> is fully adsorbed only in selected cases. Testing alcohols (<jats:styled-content style=\"fixed-case\">C<\/jats:styled-content>7\u2013<jats:styled-content style=\"fixed-case\">C<\/jats:styled-content>9) as mobile phase with <jats:styled-content style=\"fixed-case\">H<\/jats:styled-content>ypercarb\u2122 indicates that all stereoisomers of PP are selectively adsorbed and desorbed when a solvent gradient alcohol\u21921,2,4\u2010trichlorobenzene is used at 160\u00b0C. The retention of all stereoisomers of <jats:styled-content style=\"fixed-case\">PP<\/jats:styled-content> increases with the polarity of the alcohol. Linear <jats:styled-content style=\"fixed-case\">PE<\/jats:styled-content> is retained on <jats:styled-content style=\"fixed-case\">H<\/jats:styled-content>ypercarb\u2122 even from 1,2\u2010dichloro\u2010 and 1,2,4\u2010trichlorobenzene, when a temperature below 120\u00b0C is applied, while it is not retained from these solvents at higher temperatures. All stereoisomeric forms of <jats:styled-content style=\"fixed-case\">PP<\/jats:styled-content> are not adsorbed under the same conditions. Some of the tested new sorbent\/solvent systems have potential to be applied in routine analysis of industrially synthesised polyolefins.<\/jats:p>","DOI":"10.1002\/jssc.201201121","type":"journal-article","created":{"date-parts":[[2013,4,25]],"date-time":"2013-04-25T02:25:32Z","timestamp":1366856732000},"page":"2063-2071","source":"Crossref","is-referenced-by-count":9,"title":["Carbonaceous sorbents for high\u2010temperature interactive liquid chromatography of polyolefins"],"prefix":"10.1002","volume":"36","author":[{"given":"Rajesh","family":"Chitta","sequence":"first","affiliation":[{"name":"Fraunhofer Institute for Structural Durability and System Reliability Division Plastics Group Material Analytics Darmstadt Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tibor","family":"Macko","sequence":"additional","affiliation":[{"name":"Fraunhofer Institute for Structural Durability and System Reliability Division Plastics Group Material Analytics Darmstadt Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert","family":"Br\u00fcll","sequence":"additional","affiliation":[{"name":"Fraunhofer Institute for Structural Durability and System Reliability Division Plastics Group Material Analytics Darmstadt Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matthew","family":"Miller","sequence":"additional","affiliation":[{"name":"The Dow Chemical Company Freeport TX USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rongjuan","family":"Cong","sequence":"additional","affiliation":[{"name":"The Dow Chemical Company Freeport TX USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Willem","family":"deGroot","sequence":"additional","affiliation":[{"name":"The Dow Chemical Company Freeport TX USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2013,7]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-662-03910-6"},{"key":"e_1_2_7_3_1","volume-title":"HPLC of Polymers","author":"Pasch H.","year":"1998"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-75799-0"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/3-540-53135-1_4"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/app.1994.070520403"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/jssc.201000516"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1021\/ma900979n"},{"key":"e_1_2_7_9_1","first-page":"076","volume":"8","author":"Van Damme F.
