Abstract
The conformational properties of poly(acrylate) with L-aspartic acid-based side dendrons of the first and second generations with hexyloxycarbonyl end groups have been studied by the methods of molecular hydrodynamics. Regularly branched dendrons are separated from the main chain by a benzamide fragment. The degree of polymerization of the main chain varies within 30-and 50-fold intervals for the dendrons of first and second generations, respectively. Mark-Kuhn-Houwink equations have been derived for poly(acrylate) in bromoform and dichloroacetic acid containing lithium chloride additives. The experimental results are discussed in terms of the models of the wormlike chain, weakly bent cylinder, and solid ellipsoid of revolution. On the basis of translational and rotational friction data, the persistent length of poly(acrylate) in bromoform and dichloroacetic acid containing small amounts of lithium chloride has been estimated.
