Repulsive electrostatic interactions between the polyions lead to a decrease of scattering, intensity at small values of the scattering vector q followed by a more or less pronounced interaction peak. The position of the maximun varies with polyion concentration and is strongly affected by the counterion charge. Addition of simple electrolyte to the solution causes an increase of the forward scattering; at sufficient concentration of added salt the peak vanishes and the behaviour of the system becomes similar to the solution of neutral polymer"},{"@xml:lang":"sl","#text":"Z metodo ozkokotnega rentgenskega sipanja smo obravnavali raztopine litijeve, stroncijeve, ter mešanice litijeve in stroncijeve soli polistirensulfonske kisline. Zaradi odbojnih elektrostatskih interakcij med poliioni se v območju nizkih vrednosti valovnega vektorja intenziteta sipanja zmanjša, zato se pojavi bolj ali manj izraziti interakcijski pik. Lega le tega se spreminja s koncentracijo polielektrolita ter je močno odvisna od naboja protiionov. Ioni enostavne soli, ki jo dodamo raztopini polielektrolita, senčijo reakcije med poliioni. Intenziteta sipanja pri majhnih kotih se zato poveča; pri dovolj visoki koncentraciji dodane soli interakcijeski pik izgine, obnašanje raztopine polielektrolita pa postane podobno raztopini nevtralnega polimera"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:doc-PZVPNJHI","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-PZVPNJHI"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-PZVPNJHI/814d0b3c-f2b9-47c9-ae9e-4b1896c5b586/PDF"},"edm:rights":{"@rdf:resource":"http://creativecommons.org/licenses/by/4.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Slovensko kemijsko društvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:doc-PZVPNJHI/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-PZVPNJHI"}}}}
