4/15/2023 0 Comments Methyl functional group![]() In organic chemistry, the term alcohol refers to a compound containing the OH (hydroxy) group. It is an organic compound that contains a hydroxyl functional group attached. Alcohol is a functional group that you are probably familiar with. The inherent viscosity of the synthesized polyimides was 0.65 dl/g for BCDA-Durene and 0.96 dl/g for BCDA-mPDA, respectively, which indicates the moderate molecular weight of the polymers. Predict the organic product of the reaction of 2-methylpropan-1-ol with. Functional groups affect molecular function. In addition, these new polymers were soluble in various organic solvents such as dimethylformamide (DMF), dimethylsulfoxide (DMSO), and N-methyl-2-pyrrolidone (NMP). Finally, testosterone has a methyl group attached to it (3) which estradiol lacks. XRD results showed that the presence of methyl bulky groups has led to increasing of amorphous regions in the polymer structure. FTIR and 1H-NMR results confirmed the chemical structure of the synthesized polyimides. The synthesized polyimides were characterized by proton nuclear magnetic resonance (1H-NMR), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), inherent viscosity measurement, and solubility test. In this work, two semi-aromatic polyimides (BCDA-mPDA and BCDA-Durene) were successfully synthesized from bicyclooct-7-ene-2,3,5,6-tetracarbocylic dianhydride (BCDA), 1,3-phenylenediamine (mPDA), and 2,3,5,6-tetramethyl-1,4-phenylenediamine (Durene) to investigate the effect of methyl functional groups on physicochemical and structural properties of the synthesized polyimides. The only other substituent is a methyl group, and numbering the carbon chain starting from the one containing the alcohol group and moving toward the methyl. Aromatic polyimides have been attracted more attention in comparison with other polymeric materials, because of their excellent properties, such as high thermal stability, mechanical strength, and chemical resistance. ![]() ![]() ![]() It is crucial to design and develop new polymers with desirable characteristics. Functional groups which contain a nitrogen atom linked by single bonds to alkyl groups, aryl groups, hydrogen groups, or some combination of these groups are called amino groups. ![]()
