“…Glass-transition temperatures of PSt and PCL homo-polymers are reported to be 371.5 and 211.1 K, respectively [32,33]. These data are in agreement with the results presented in this work, which can be considered as reliable enough to start with for further calculations.…”

In this study, a quantitative structure-property relationship (QSPR) study is carried out to estimate the physical properties of substituted polypyrrole (PPy) and polyparaphenylene (PPP). The effects of the substituted side-chains composed of ε-caprolactone, ethylene and styrene oligomers on the glass transition temperature, cohesive energy and dielectric constant of PPy and PPP are studied and the results are analyzed in terms of backbone structure, the type and the length of the side-chains. It is shown that the T g of the polymers can be lowered upon substitution of flexible side-chains. The cohesive energy is higly dependent on the the strength of the non-bonded interactions and it is increased by incorporation of flexible side-chains. The dielectric constant of the polymers is found to be increased depending on the polarizability and the dipole moment density of the side-chains.

“…This clearly indicated that thesurface modification was permanent due to either the chemical bond formation between PDMS oligomers and PA6 or very strong hydrogen bonding between urea and amide groups. Surface modification of PVC with PCL-PDMS-PCL copolymers has also been investigated (150,(328)(329)(330). Blends with different concentrations of silicone copolymers were generally prepared by solution casting.…”

A comprehensive survey of the recent developments on the synthesis, properties and applications of silicone containing copolymers is provided. Influence of (−R 2 Si−O−) backbone composition on the physicochemical properties of silicone copolymers, such as thermal transitions, solubility parameter and surface tension is discussed. Preparation and properties of well-defined α,ω-reactive organofunctionally terminated (telechelic) silicone oligomers and their utilization in the preparation of a wide range of block and segmented copolymers through step-growth,anionic, ring-opening and living free-radicalpolymerization techniques are provided. Use of silicone oligomers in the modification of polymeric network structures is also discussed. Special emphasis is given to the discussion of the effect of silicone oligomer and organic segment structure and molecular weight on the morphology and surface and bulk properties of the resultant silicone containing copolymers and networks.

“…Because the PSt‐ g ‐PCL exhibit a single glass transition (Tg = 71°C), which is considerably lower than Tg of PSt‐N3, it could assume some miscibility between the PSt and PCL blocks . On the other hand, the presence of only one Tg of PVC‐ g ‐PCL lower than the Tg of PVC‐N 3 clearly indicates that PCL acts as a macromolecular plasticizer for the PVC …”

This review is about the reactive plasticizer. Plasticizers are small molecules with low molecular weight. These compounds typically have an esteric structure. The plasticizers reduce the glass transition temperature, and the viscosity of the polymer also enhances the flexibility and processability of polymer materials. The main problem of these additives is that, over time, they migrate from the polymeric matrix and exude to the surface of polymeric matrix. As a result, the physical and mechanical properties of the polymer are affected. Various strategies, such as increasing molecular weight of plasticizer, selection of oligomeric structure for plasticizer, and adding nanoparticles of minerals, have been investigated to reduce and eliminate migration.An approach that has recently been of great interest to researchers is the use of reactive plasticizers. In this approach, plasticizers covalently bond to the polymeric chains and prevent migration.
