In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Synthesis and application of aqueous cationic polycarbodiimide crosslinking agent, published in 2011-03-03, which mentions a compound: 707-61-9, Name is 4-Methyl-1-phenyl-2,3-dihydro-1H-phosphole 1-oxide, Molecular C11H13OP, SDS of cas: 707-61-9.
Aqueous cationic polycarbodiimide crosslinking agent was synthesized with isophorone diisocyanate(IPDI), polypropylene glycol(PPG400), N,N-di-Me ethanolamine(DMEA) and 3-methyl-1-phenyl-2-phospholene-1-oxide(MPPO) as raw materials. The influences of synthesis conditions such as the dosage of catalysis agent, reaction time, reaction temperature, nitrogen jet velocity, hydrophilic end-blocking agent, blocking temperature, and the dosage of end-blocking agent on the properties of product were investigated. The developed crosslinking agents were introduced to protein finishing agent. And it is found that the properties of obtained finishing film agent are better in the water resistance, alk. resistance, solvent resistance and flexibility. Also, the tensile strength of film increases with a little decrease in brightness and transparency.
Compound(707-61-9)SDS of cas: 707-61-9 received a lot of attention, and I have introduced some compounds in other articles, similar to this compound(4-Methyl-1-phenyl-2,3-dihydro-1H-phosphole 1-oxide), if you are interested, you can check out my other related articles.
