5. 4. Synthesis and characterization of dendritic macromolecules based on 2,2-bis(hydroxymethyl)propionic acid

   Författare :Henrik Ihre; KTH; []
   Nyckelord :;

   Sammanfattning : Dendrimers are a relatively new type of macromolecules characterized by a well-defined, highly branthed, layered structure with a multitude of chain ends, adopting a globular shape at higher molar masses. Dendrimers are usually constructed from ABx type of monomers in either one of the two step-wise approaches known as thedivergentor theconvergent growth approach. LÄS MER

7. 5. Chiral Liquid Crystalline Side-Chain Polymers. Design, Synthesis and Properties

   Författare :Magnus Svensson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lateral substituent; electro-optic; ferroelectric; molar mass; polymer; side-group; thin film; polysiloxane;

   Sammanfattning : The potential use of chiral liquid crystalline materials, low molar mass as well as polymers, in technical applications has been recognized for some decades now. A number of interesting phenomena based on the spontaneous ordering of the liquid crystal forming molecules are strong reasons for the research effort in this area. LÄS MER
