Abstract

U ovom su radu provedena istraživanja utjecaja mikro celuloze kao punila u različitim masenim udjelima (1, 2,5 i 5 %) u polimernu maticu homopolimera poli(metil-metakrilata) i kopolimera poli(metil-metakrilat-ko-(dimetilamino)etil-metakrilata). Uzorci su sintetizirani radikalskom (ko)polimerizacijom u otapalu toluenu. Sintetizirani polimeri i pripadni kompoziti su osušeni i prešani, nakon čega su analizirani kromatografijom na propusnom gelu (GPC), diferencijalnom pretražnom kalorimetrijom (DSC), termogravimetrijskom analizom (TGA) i pretražnom elektronskom mikroskopijom (SEM). Temeljem rezultata analiza određen je utjecaj udjela punila na raspodjelu molekulskih masa i disperznost, toplinske prijelaze, toplinsku stabilnost te morfologiju sintetiziranih kompozita.

Abstract (english)

In this study the addition of micro cellulose as filler in different mass fractions (1, 2,5 and 5 %) in polymer matrix of homopolymer poly(methyl methacrylate) and copolymer poly(methyl methacrylate-co-(dimethylamino)ethyl methacrylate) was investigated. Samples were synthesized by radical (co)polymerization in toluene. Dry polymer samples were melt-pressed and analysed with gel permeation chromatography (GPC), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and scanning electronic microscopy (SEM). As the result of the analyses, influence of mass fraction of filler on molar mass distribution, dispersity, glass transition temperature, thermal stability and morphology was determined.
