Lipidic additives for polymeric materials
F
acing the toxicity of many plastics and the increasingly drastic regulations, many studies on novel additives, especially
bio-based additives for polymers are sought. Herein, we illustrated this keen interest with bio-based plasticizers and
surfactants as alternatives to phthalate plasticizers and nonylphenol ethoxylated surfactants, respectively. Poly(vinylchloride)
(PVC) is one of the most attractive industrial plastics (biomedical, textile industry, plastic toys, packaging) because available
as rigid or soft materials. In the latter case, flexibility and processability come from a plasticizer-additive in high amount
(30-50 %w/w). Nowadays, the most widespread plasticizers are the phthalates even if severe public health-care issues as
reprotoxic and endocrine disruptor effects are attested. Most of phthalates will be banned by standards and regulations
(Reach Annex XIV). In our lab, two generations of phthalate-free plasticizers have been developed using green chemistry.
Phosphonated lipids prove to be an efficient additive as primary plasticizers for PVC as well as flame retardants. Otherwise,
cardanol-based plasticizers of PVC reach good PVC plasticizing properties and reveal no impact on environment and
no endocrine perturbation activity. These results are attractive in order to replace phthalates in soft PVC formulation
industry. Among the nonionic surfactants, Nonylphenol Ethoxylated (NPE) has widely demonstrated their efficiency even
if a high toxicity to aquatic organisms was proved. Regarding the many sectors including textile processing, pulp and paper
processing, paints, resins and protective coatings, oil and gas recovery in which they were employed, substituents seem to
be a major issue. It has been reported that the ethoxylation of cardanol, bio-sourced lipidic phenol, produced a nonionic
surfactant characterized by a low biodegradability. Inspired by these results, we investigated a series of surfactants based on
cardanol and Polyoxazoline (POx) technology knowing the POx are well-known to be an alternative to PEG.
Biography
Vincent Lapinte is an Assistant Professor at the Polymer Department of the Institute of Materials Charles Gerhardt of Montpellier (ICGM-France). His area of
expertise concerns the bio-based polymers especially peptides and pseudo-peptides such as polyoxazolines regarding synthesis and self-assembly aspects. Bio-
based building blocks for polymers were also investigated. He has published more than 50 papers in reputed journals and 7 patents. He also has Co-Supervised
18 PhD and 12 post-doctoral.
