Kompatibilizacija mešanic polipropilena in polistirena z blokkopolimeri : doktorska disertacija
Radonjič, Gregor
Proučevali smo kompatibilizacijske učinke blokkopolimerov stirena poli(stiren-b-butadien-b-stirena) (SBS), poli(stiren-b-etilen-co-propilena) (SEP) in dveh tipov ...poli(stiren-b-etilen-co-butilen-b-stirena) (SEBS), ki se razlikujeta glede na molski masi, na morfologijo in mehanske ter predelovalne lastnosti nemešljive mešanice polipropilena (PP) in polistirena (PS) različnih masnih razmerij. Ugotovili smo, da kompatibilizatorji ne delujejo le površinsko aktivno, ampak vplivajo tudi na kristalizacijske procese delno kristalinih polimerov. Spremembre v kristalni strukturi PP ob dodatku kompatibilizatorja smo povezali s spremembami mehanskih lastnosti in deformacijskimi procesi pri nateznih in udarnih obremenitvah. Blokkopolimeri stirena znižujejo medfazno napetost, preprečujejo koalescenco in izboljšajo medfazno adhezijo, kar vodi do izboljšanih mehanskih lastnosti. Ugotovili smo da je kompatibilizacijska učinkovitost blokkopolimerov stirena v mešanicah PP/PS zelo odvisna od masnega razmerja PP/PS, koncentracije kompatibilizatorja, kemijske strukture kavčukovega bloka, molske mase kompatibilizatorja in viskoznostnega razmerja PS in PP.
