Khoom cim npe

2,5-Furandione, dihydro-, monopolyisobutylene derivs CAS 67762-77-0 yog dab tsi?

(PIBSA, CAS 67762-77-0) yog cov tshuaj ua haujlwm ua ke los ntawm cov tshuaj tiv thaiv ntawm polyisobutylene (Mn = 1000) thiab txiv neej anhydride. Nws muaj kev ua haujlwm saum npoo, dispersibility thiab thermal stability, thiab yog ib qho tseem ceeb nruab nrab rau kev npaj ntawm ashless dispersants, emulsifiers thiab lubricant additives. Cov pawg polar thiab cov ntu tsis-polar hauv nws cov qauv molecular muab cov khoom lag luam tshwj xeeb "amphiphilicity"
