Usage

General Description

4,4'-(1,3-Propanediyl)dioxydianiline, also known as PDDA, is a diamine compound with the chemical formula C9H14N2O2. It is a colorless to light yellow liquid with a slightly amine-like odor. PDDA is commonly used as a curing agent in epoxy resins, where it acts as a hardener that helps to crosslink and strengthen the resin. It is also used in the production of polyurethane foams and coatings. PDDA is considered to be a skin and eye irritant and should be handled with care in a well-ventilated area. Additionally, it should be stored in a sealed container away from heat and direct sunlight to prevent degradation.

Design and characterization of novel bis-benzamide liquid crystalline materials

A new homologous series of symmetric, bent-shaped bis-benzamide dimers have been prepared. Several 1,n-bis(p-aminophenoxy)alkanes (n = 3, 5, 9,10,11) were employed as spacers and p-hexyloxy tails have been synthesized and appended to the spacers by amide linking groups. Different important parameters were explored using computational analysis by semi empirical method. The experimental results were correlated with theoretical studies and relationship between molecular structure and mesogenic behavior has been established. The mesomorphic properties of the resultant dimers were characterized by differential scanning calorimetry (DSC) and polarized optical microscopy (POM) equipped with a hot stage. Change in mesomorphic properties with change of methylene spacers was observed. Enantiotropic mesogenic behavior was exhibited by D3A6, D10A6 and D11A6 and the needle like and blurred schleiren textures were observed. It was observed that increased methylene spacers chain length decreased the melting temperatures. Thermogravimetric analysis revealed the thermal stability of dimers upto 360 °C.

Synthesis and characterization of new optically active poly(amide-imide)s based on n-trimellitimido-l-amino acid and trimethylene units

Six new optically active poly(amide-imide)s (8a-f) were synthesized through the direct polycondensation reaction of 1,3-bis(4-aminophenoxy) propane (4) with six different derivatives of N-trimellitimido-L-amino acid (7a-f) in a medium consisting of N-meth
