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

   Author : Henrik Ihre; KTH; []
   Keywords : ;

   Abstract : 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. READ MORE
