“…Blends of PVC and polyesters in the form of foils 0.4 mm thick were prepared on a Polymix 80T two‐roll mill, roller size 80/300 mm, slip 1.2 (rotation velocity ratio 22:19). Rolling temperature 180°C ± 0.1°C, blend preparation time 8 min (optimum period of time with respect to the TS and the notch impact strength of blends10). The specimens (thickness 0.4 or 4 mm) were obtained by 5 min compression at 195°C and 30 MPa.…”

“…PVC and PEA containing 20–70 mol % CLO units are immiscible; the highest values of notch impact strength were achieved for an equimolar ratio of CLA/CLO structural units in PEA. To further increase the toughness of the PVC/PEA blends, it is possible to apply a higher content of PEA combined with a small amount of PCLO which improves the miscibility of both components leading to a microheterogeneous two‐phase system 10…”

“…Another possibility is to incorporate in the PCLO chains different structural units, e.g., e-caprolactam (CLA), possibly also aliphatic or aromatic ester units. 6,[10][11][12] Aliphatic-aromatic copolyester based on e-caprolactone (CLO) and ethylene terephthalate containing 60 mol % or more CLO structural units is fully miscible with PVC and exhibits plasticizing effect. 11 A product of the copolymerization of CLO and solvolyzed recyclate from disposed PET bottles represents also a promising plasticizer.…”

Properties of the blends of Poly(vinyl chloride) (PVC) and poly(e-caprolactone) (PCLO) and copolyesters based on e-caprolactone and L-lactide (LLA) prepared by rolling were studied. Incorporating the LLA units into the structure of PCLO the content of the crystalline phase was controlled. Miscibility of the blends was assessed using DMA, and basic mechanical properties were correlated with the type and content of the polymer plasticizer. The PVC blends containing up to 20 wt parts polyesters were miscible. The presence of the LLA units in the copolyester influenced negatively the thermal stability. On the other hand even small content of copolyester in the blend enhanced the resistivity against aging.

Thiophene and their derivatives products are some of the oldest and best known class of nitrogen and sulphur containing compounds. In recent years there has been considerable interest in the thiophene -based family of materials due to the wide range of antimicrobial activity properties when incorporated into polymers and their composites. In this research new modified polyesteramide resin compositions which are prepared by partial replacement of phthalic anhydride (PA) with 3,6-dichloro bezo[b]-thiophene-2carbonyl glutamic acid (DCBTGA), as a new source of the dibasic acid and as preservative against microbiological attack with N, N-bis -(2-hydroxyethyl) linseed oil fatty acid amide (HELA) as source of polyol. These new source of dicarboxylic acid materials and new modified polyesteramide resin are confirmed by IR and NMR spectral analysis. The coating performance of the resins is evaluated using international standard test methods (ASTM) and involved the measurement of phyisco-mechanical properties such as viscosity, drying time, specular gloss, pencil hardness, adhesion, flexibility and The results show that the modification enhances both phyisco-mechanical and chemical properties The new antimicrobial polyesteramide resins is characterized using standard (Kathon LX biocide) in different excess -OH formulations to reach the best formula against bacteria and fungi. The studies showed promising results as biocide coatings.

Five kinds of polyepichlorohydrin (PECH) of different molecular weights were synthesized and characterized by gel permeation chromatography (GPC). Mechanical blending was used to mix PECH and poly(vinyl chloride) (PVC) together. The blends of different PVC/ PECH ratios were characterized by thermogravimetric analysis (TGA), tensile tests, differential scanning calorimetry (DSC), and dynamic mechanical analysis (DMA). TGA results show the thermal stability of PVC/PECH blends is desirable. Tensile tests indicate elongation at break is raised by increasing both the amount and the molecular weight of PECH. DSC is used to determine the glass transition temperature of PECH, and a quite low T g is obtained. DMA results indicate that PECH has a perfect compatibility with PVC, when PECH concentration is below 20 wt %. There is only one peak in each tan d curve, and the corresponding T g decreases as PECH amount increases. However, above 20 wt %, phase separation takes place. The molecular weight of PECH also has a great influence on the glass transition temperature of the blends. This study shows that PECH is an excellent plasticizer for PVC, and one can tailor the glass transition temperature and tensile properties by changing the amount and the molecular weight of PECH.
