Recent Attempts in the Design of Efficient PVC Plasticizers with

A PVC blend with synthesised hyperbranched plasticizers with the highest ratio (15:1) of caprolactone: polyester (named HEPCL) exhibited the lowest T performed better than DOP in terms of mechanical properties, and at the same time exhibited the highest migration resistance. 2.1.3.

synthesis and properties of isosorbide-based eco-friendly plasticizers

Synthesis and Properties of Isosorbide-Based Eco-friendly Plasticizers

The solubility parameter is an index related to the polarity; similar values for PVC and plasticizer indicate good compatibility . Compatibility between PVC and the plasticizer was evaluated in terms of the solubility parameter (¦Ä) (Table 3). The ¦Ä value of PVC was 9.7, and the ¦Ä values of isosorbide-based plasticizers decreased with

Development of a Highly Efficient Environmentally Friendly Plasticizer

The new environmentally friendly plasticizer has good compatibility with PVC and high thermal stability. The effectiveness of the plasticizing action of adipate based on the glass-transition temperature was 132.2 ¡ãC in relation to pure PVC and 7.7 ¡ãC in comparison to compounds based on DOP.

Designing of Green Plasticizers and Assessment of the Effectiveness of

To study the effect of the obtained plasticizers on the biodegradation of PVC plastics, PVC films of the following composition were obtained: 100 parts by weight of PVC; 40 parts by weight of the plasticizer; 3 parts by weight of calcium stearate stabilizer. To assess the biostability, the obtained film samples were tested by a mycological test.

Self-Plasticized PVC Prepared by Introducing Fatty Acid to the PVC with

Ester-amide of ricinoleic acid was synthesized by a two-step reaction with di-Bu amine and benzoic acid; and then utilized as primary plasticizer in PVC. Ester-amide plasticizer was added up to 40 phr in PVC; and the prepd. PVC sheets were characterized for mech., x-ray diffraction, thermal, rheol., colorimetric, and exudation properties.

An efficient cold-resistant strategy: Synthesis and application of

By means of capability tests, we detected that the T i (initial degradation temperature) of PVC films plasticized with oleate plasticizers was 40 ¡ãC higher than that of DOA/PVC and 20 ¡ãC higher than that of DOTP/PVC. More importantly, in addition to illustrious migration resistance, they could maintain remarkable flexibility in cold environments as well.

Effects of these MDPs will be discussed by comparing the performance metrics of the corresponding groups or pairs of plasticizers, including the heat of mixing ¦¤ H for plasticizer compatibility with PVC, Young¡¯s modulus of plasticized PVC for its efficiency, and plasticizer mean square displacement (MSD) for its migration tendency. In this paper, we will first give an overview of key
