RT-101 CAS :34052-90-9, 1, 3-bis (4, 5-dihydro2-oxazole) benzene (dioxazoline) is an important organic reaction intermediate, which contains two evil ? functional groups in its structure, and its chemical properties are quite active. At a certain temperature, it can carry out ring-opening reaction with carboxyl group, acid anhydride, amino group, epoxy group, euclidyl group, phenol hydroxyl group, isocyanate group, etc., which increases the molecular chain and significantly improves the viscosity of the resin, so it is often used as a chain extender or crosslinking agent of polymers.

1, 3-bis (4, 5-dihydro2-oxazole) benzene (dioxazoline) is widely used as chain extender with tree esters containing carboxyl group, acid anhydride, amino group, epoxy group, lucyl group, phenol hydroxyl group, isocyanate group, etc. The recommended dosage theory for adding polyethylene terephthalate (PET) is 0.2%-2%, generally 0.8% (coupling reaction and sealing reaction), twin-screw extrusion, and the time is short. The reactivity is above 80 degrees and below 260 degrees, and the general twin-screw extrusion temperature is 210-220 degrees.
