We consider the complex polymer system, consisting of a ring polymer connected to the f_{1}-branched starlike structure, in a good solvent in the presence of structural inhomogeneities. In particular cases f_{1}=1 and f_{1}=2, such a system restores the synthesized tadpole-shaped polystyrenes [Doi et al., Macromolecules 46, 1075 (2013)MAMOBX0024-929710.1021/ma302511j]. We assume that structural defects are correlated at large distances x according to a power law x^{-a}. Applying the direct…

Disorder effects on the static scattering function of star branched polymers

We present an analysis of the impact of structural disorder on the static scattering function of f-armed star branched polymers in d dimensions. To this end, we consider the model of a star polymer

Spatial correlations in a self-repelling ring polymer

The scattering structure function SN(q) of a large flexible ring polymer with N monomers in a good solvent is calculated as a universal expansion in the variable q2<RG2≳, where <RG2≳ denotes the mean

Star shaped polymers : a model for the conformation and its concentration dependence

We propose a model giving the conformation of a star shaped polymer by taking into account the radial variation of the monomer concentration ϕ( r). For an isolated star when increasing r (at the

Static scattering function for a regular star-branched polymer

The static scattering function for a regular star-branched polymer is calculated in the full excluded-volume limit with renormalization group techniques, and a closed-form expression for the

On the Influence of Topological Catenation and Bonding Constraints on Ring Polymers

The ring structure of certain polymers in nature, like proteins and DNA indicates a benefit compared with the linear form. Transcriptional regulation in higher eukaryotes is maintained among others

Entropy-induced separation of star polymers in porous media.

The impact of long-range-correlated quenched disorder on the entropy and scaling properties of f-arm star polymers in a good solvent is studied to find that gammaf-1, the deviation from its mean field value is amplified by the disorder once the authors increase delta beyond a threshold.

Conformational properties of complex polymers: rosette versus star-like structures

Multiple loop formation in polymer macromolecules is an important feature of the chromatin organization and DNA compactification in the nuclei. We analyse the size and shape characteristics of

Statistics of self‐avoiding ring polymers

Some important statistical properties of the self‐avoiding freely jointed ring‐polymer model are studied. Using dynamic Monte Carlo techniques, which yield proper ring configurations, the probability
