✦ Synopsis

Monte

Carlo simulation results are presented for lattice models of uniform stars (one branch point of functionality f = 31, combs (two branch points, f = 3,3) and brushes (two branch points f = 3,4 and f = 33). We estimate the critical exponent ~( f ) , the ratio g ( f ) = (Sgf))/(Sgl)) (where ( S 2 f ) ) is the mean-square radius of gyration of a structure having f branches and N monomers), and the meansquare end-to-end branch lengths, as a function of the number and arrangement of branches. Comparisons with theoretical predictions and experimental data are made where poqsible, leading to a test of some predictions, and a suggestion concerning future experiments.

## Abstract The simple cubic‐lattice model of polymer chains was used to study the dynamic properties of adsorbed, branched polymers. The model star‐branched chains consisted of __f__ = 3 arms of equal lengths. The chain was modeled with excluded volume, that is, in good solvent conditions. The onl

Dynamic Monte Carlo simulations of simple models of star-branched polymers were conducted. A model star macromolecule consisted of f = 3 arms of equal length with a total number of polymer segments up to 800. The chain was confined to a simple cubic lattice with simple nearest neighbor attractive in

Pure amyloses obtained from various starches contain limited numbers of branch linkages and are mixtures of branched and unbranched moleculesl-14, although amyloses are defined as unbranched molecules. However, amyloses of various origins have been characterised generally without separation of the b
