Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 34052-90-9, Name is 1,3-Bis(4,5-dihydrooxazol-2-yl)benzene, molecular formula is , belongs to oxazolidines compound. In a document, author is Chen, Hong, Recommanded Product: 1,3-Bis(4,5-dihydrooxazol-2-yl)benzene.
Synthesis of Polyoxazolidines and Their Application in Polyurethane Modification
2,2-Dimethyl-N-hydroxyethyl-1,3-oxazolidine (OX) and two kinds of poly-oxazolidines based on OX:malonic acid diethyl-2, 2-dimethyl-N-hydroxyethyl-1, 3-oxazolidine ester (OX1) and 1, 1, 5, 5-pentane end tetracarboxylic acid tetra-2,2-dimethyl-N-hydroxyethyl-1,3-oxazolidine ester (OX2) have been designed and successfully synthesized. Their structures. have been confirmed by C-13-NMR, ESI-MS, elemental analysis and FTIR. Their applications as latent curing agents in single component polyurethane (SPU) systems have been investigated. The results show that the SPU system cured in air without oxazolidine forms lots of foaming and can be swelled, its tensile strength is 3.2 MPa and the elongation at break is 364%. However, the tensile strength and elongation at break of the SPU system cured with the synthesized OX2 can reach 27.2 MPa and 457%, about 9 times and 1.26 times as compared with those the cured SPU system without OX, respectively. The addition of the synthesized OX1 or OX2 can greatly improve the apparent performance, mechanical properties and thermal stability properties of the cured SPU system.
