  2. 1. Waterborne Alkyd-Acrylic Hybrids with High Solids Content -Preparation and Properties-

    Author : Mehrnoush Jowkar Deriss; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biopolymers; Polymer technology; Polymerteknik;

    Abstract : The work presented in this thesis concerns the preparation, characterization and film formation of a waterborne alkyd-acrylic hybrid system with high solids content of about 80 %. The alkyd-acrylic hybrids were prepared by slowly adding a linseed oil alkyd to an acrylic latex dispersion under stirring. READ MORE

  4. 2. Water-based Flexographic Printing on Polymer-coated Board

    Author : Maria Rentzhog; Mark Rutland; Joseph Aspler; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Surface and colloid chemistry; Yt- och kolloidkemi;

    Abstract : This doctoral thesis comprises three studies dealing with water-based flexography on polymer-coated boards, which have been presented in the five papers included at the end of the thesis. The first study (covered in three papers) presents results from characterisation of a matrix of water-based inks with respect to their rheology, surface tension, wetting, and fulltone printing performance on PE-coated board.

  5. 3. Preparation and characterisation of biodegradable microspheres for the delivery of bioactive compounds

    Author : Cecilia Sturesson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacy; FARMACI; PHARMACY; FARMACI; galenisk farmaci; Pharmaceutics;

    Abstract : The incorporation of bioactive compounds into biodegradable polymer microspheres has several advantages. Firstly, the drug substance is protected from physiological degradation. Secondly, using microspheres from polymers with different degradation mechanisms, it is possible to design different release profiles with desired release rates. READ MORE

  6. 4. Modification and Utilization of Wood Hydrolysates

    Author : Marie Svensson; Ann-Chrisitne Albertsson; Petra Mishnick; Ulf Gedde; KTH; []
    Keywords : wood hydrolysate; hemicellulose; microsphere; hydrogel;

    Abstract : Polysaccharides have been used for many years in a variety of products such as food, fuel supply and industrial products. During recent years there has been an increasing interest in a group of polysaccharides, hemicelluloses, due to their highly availability, renewability and potentially low price. READ MORE
