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 polycarbodiimide crosslinking agent(II): aqueous anionic polycarbodiimide crosslinking agent, published in 2011-08-03, which mentions a compound: 707-61-9, Name is 4-Methyl-1-phenyl-2,3-dihydro-1H-phosphole 1-oxide, Molecular C11H13OP, Recommanded Product: 707-61-9.
Aqueous anionic polycarbodiimide crosslinking agent was synthesized with isophorone diisocyanate(IPDI), sodium hydroxyethyl sulfonate(SHES) and 3-methyl-1-phenyl-2-phospholene-1-oxide(MPPO) as raw material. The influences of different synthesis conditions such as the hydrophilic end-blocking agent and temperature, as well as the dosage of end-blocking on the blocking reaction were investigated and the optimal technol. condition was obtained. The developed crosslinking agents were introduced to acrylic finishing agent. It show that tensile strength of the film increases from 2.813MPa to 6.147MPa; the swelling rate in water, 0.05mol/L NaOH, Bu acetate decreases from 52.3% to 26.4%, 202.4% to 140.4%, 843.2% to 354.8% resp.; and the rub fastness of dry and wet are improved by adding the crosslinking agent to the acrylic finishing agents.
Although many compounds look similar to this compound(707-61-9)Recommanded Product: 707-61-9, numerous studies have shown that this compound(SMILES:CC1=CP(CC1)(C2=CC=CC=C2)=O), has unique advantages. If you want to know more about similar compounds, you can read my other articles.
