1. Combustion dynamics and melt dripping of ethylene-acrylate copolyer composites
Sammanfattning : The degradation and combustion of blends of ethylene-acryalte copolymer with calcium carbonate and silicone were studied by a combination of flammability tests, in-situ measurements and analytical experiments. Compounds of poly(ethylene-co-methacrylic acid) blended with precipitated calcium carbonate nanoparticles were prepared. LÄS MER
2. Mass-Transport through Interfaces
Sammanfattning : Many of the products in our daily life consist of layered structures, where packaging materials and wound care products can be mentioned as examples. These structures often consist of different kind of polymeric materials and between these materials interfaces are formed. LÄS MER
3. Polymer Bound Water-Soluble Metal Phosphine Complexes-Preparation, Characterisation and Catalytic Application
Sammanfattning : Four new water-soluble phosphines have been prepared by utilising water-soluble polymers as charge carrying units. Coupling of methyl-4-(diphenylphosphino)-benzyl-amine or 4-diphenylphosphino benzaldehyde to poly-acrylic acid and poly-ethylene imine, respectively, afford the ligands PAA-PNH and PEI-PNH. LÄS MER
4. Water-assisted mixing and compression moulding of ethylene-acrylic acid copolymer reinforced with nano-cellulose
Sammanfattning : The concerns regarding aspects of global warming, depleting oil resources, accumulation of plastics in landfills has served as motivation to move towards utilizing sustainable and renewable resources to fulfil our needs. In the present work, the reinforcing capabilities of cellulose nanofibrils (CNF) and modified/unmodified cellulose nanocrystals (CNC) based composites prepared through water-assisted mixing, drying and compression moulding was explored.

5. Phase Behavior and Solution Properties of Aqueous Polyion-Surfactant Ion Systems
Sammanfattning : Polyelectrolytes and oppositely charged surfactants interact through attractive electrostatic forces, which in many cases lead to phase separation already at low total concentrations. During the past 10-15 years investigations of these systems have been simplified through the use of complex salts that consist of surfactants with polymeric counterions in a 1:1 charge stoichiometry (no excess simple counterions present).
