  4. 4. Crystallisation of star polyesters with poly (ε-caprolactone) arms approaching the problem of early stages in polymer crystallisation

    Detta är en avhandling från KTH Royal Institute of Technology

    Författare :Eugenia Núñez; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technology; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The knowledge regarding early stages in polymer crystallisation remains inconclusive due to experimental limitations. The reason is that the initially formed polymer crystals rearrange rapidly at the crystallisation temperature. Faster experimental techniques or simulation would be suitable alternatives to approach the problem. LÄS MER
