    Effect of Modified Cardanol as Secondary Plasticizer

    This study represents the first attempt to prepare a novel cardanol-based plasticizer. Modified cardanol (MC, i.e., phosphorylated cardanol) containing nitrogen and phosphoric acid groups was synthesized and then incorporated into polyvinyl chloride (PVC) as the secondary plasticizer for partial substitution of dioctyl phthalate (DOP). The molecular structure of MC was characterized by Fourier

    Non-endocrine disruptor effect for cardanol based plasticizer

    Two generations of cardanol based plasticizer were reported. The first generation, cardanol ester plasticizers, CEx (Fig. 2, step A), were immiscible with PVC. Hence, they were mixed with DINP (50/50 w/w) and tested as secondary plasticizers, in order to reduce the quantity of DINP in PVC formulation.

    Effects of diffusion of a naturally-derived plasticizer

    Cardanol acetate (CA) was obtained by solvent free esterification of cardanol, and used as secondary plasticizer, by partial substitution of DEHP in soft PVC formulations. Ageing tests were performed in order to study the stability of properties of the soft PVC formulations related to plasticizer diffusion.

    Cardanol Groups Grafted on Poly(vinyl chloride)—Synthesis

    The common non-attached plasticizer based on cardanol acetate , epoxidized cardanol phenyl phosphate ester plasticizer , and epoxidized cardanol laurate are easily leached from PVC in organic solvent, which is not conducing to make PVC products long-lasting and stable. The loss of plasticizers pollutes environments and produces a potential

    Plasticizers derived from cardanol: synthesis

    Two natural plasticizers derived from cardanol (CD), cardanol acetate (CA) and epoxidized cardanol acetate (ECA), were synthesized and characterized by 1H NMR and 13C NMR. The plasticizing effects of the obtained plasticizers on semi-rigid polyvinylchloride (PVC) formulations were also investigated. Two commercial phthalate ester plasticizers, dioctyl terephthalate (DOTP) and diisononyl

    Designing Rosin-Based Plasticizers: Effect of Differently

    Polymers can be well dissolved in plasticizers when δ of the polymers and the plasticizers is the same or the difference is less than ±3.07 (J/cm 3) 1/2. 25,26 The δ value and the difference of δ between PVC and plasticizer (D) for PVC, DOP, and rosin-based plasticizers was calculated according to eqs 2 and 3, and compared in Table 2.

    Novel cellulose-based bioplastics, mainly using inedible plant resources, were produced by bonding cellulose diacetate (CDA), a modified cardanol, and additional aliphatic and aromatic components. Cardanol is a phenol derivative with a linear unsaturated hydrocarbon side chain (carbon number: 15), derived from cashew nut shells. Esterification of the modified cardanol (3-pentadecylphenoxy
