A study on the aliphatic energetic plasticizers containing nitrate ester and nitramine

The aliphatic energetic plasticizers with three and four –CH₂ between nitrate ester and nitramine were synthesized to obtain a plasticizer that is more stable than N-butyl-N-nitratoethyl nitramine (BuNENA) with two –CH₂. First, amino alcohol compounds such as propylamino propanol (PAP) and ethylamino butanol (EAB) as a precursor of energetic plasticizer were synthesized. However, unlike in BuNENA synthesis, various side reactions occurred in the nitration of amino alcohols. Fortunately, it was possible to considerably suppress the formation of side products in the nitration of PAP by using a solvent and an appropriate concentration of nitric acid. In addition, an energetic plasticizer with higher oxygen content was obtained through the nitration of intermediate, amide alcohol, which was formed in the synthesis of EAB.     

Ester‐amide based on ricinoleic acid as a novel primary plasticizer for poly(vinyl chloride)

Utilization of ricinoleic acid as a raw material for the synthesis of green plasticizer would offer an alternative to the phthalate plasticizers. Ester‐amide of ricinoleic acid was synthesized by a two‐step reaction with dibutyl 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 prepared PVC sheets were characterized for mechanical, X‐ray diffraction, thermal, rheological, colorimetric, and exudation properties. Addition of the ester‐amide plasticizer demonstrated good incorporation and plasticizing performance in PVC. Viscosity of PVC decreased with increased addition of ester‐amide plasticizer. The dark color of the synthesized plasticizer could have constraints on its application areas; however, the prepared samples illustrated negligible weight loss in the exudation test, attributed to better compatibility between them brought about by the ester, tertiary amide and polarizable benzene ring in the ester‐amide plasticizer with the C‐Cl polar linkage in PVC. © 2015 Wiley Periodicals, Inc.

Effect of plasticizer on the thermal,mechanical, and anticorrosion properties of an epoxy primer

The influence of the glass transition temperature and the mechanical and anticorrosion properties of factors such as the amount of plasticizer added to an epoxy primer were investigated by DSC (differential scanning calorimeter), DMA (dynamic mechanical analysis), stress-strain tests, salt fog spray tests, accelerated tests, and electrochemical tests. The addition of plasticizer results in a decrease in the glass transition temperature and a change in the mechanical properties. Different tests were carried out to the optimum percentage of plasticizer content (1.5–3% weight ratio to epoxy resin) required to obtain the maximum anticorrosion performance of the epoxy primer. These changes are explained by the structural-kinetic effect exerted by the plasticizer on the chemical crosslinking in the course of the epoxy network synthesis and the increase in the excess free volume.
