  1. 1. On the Size and Shape of Polymers and Polymer Complexes A Computational and Light Scattering Study

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Tomas Edvinsson; Uppsala universitet.; [2002]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Monte Carlo simulations; grafted polymers; shape description; folding complexity; clustering; percolation algorithm; light scattering; end-capped polymers; inclusion complexes; Fysik; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik; Physical Chemistry; Fysikalisk kemi;

    Sammanfattning : Detailed characterization of size and shape of polymers, and development of methods to elucidate the mechanisms behind shape transitions are central issues in this thesis. In particular we characterize grafted polymer chains under confinement in terms of the chain entanglement complexity and mean molecular size. LÄS MER

    Nyckelord :star-branched; semi-crystalline; comb-branched; ring-opening polymerization; poly ƒÕ-caprolactone ; dendritic; thermoset; low temperature curing; powder coating; UV-curing; poly 5; 5-dimethyl-1; 3-dioxane-2-one ; size exclusion chromatography; rheology;

    Sammanfattning : This thesis describes the synthesis and characterization ofbranched semi-crystalline polymers. Included in this work isthe SEC characterization of a series of dendrimers. Thebranched semi-crystalline polymers were synthesized in order toinvestigate the concept of their use as powder coatings resins. LÄS MER
