Product Description
Dioxazoline 1,3-PBO containing two carbon nitrogen oxygen and carbon-nitrogen double bonds widely used as chain extender or crosslinking agent for polymers
Description of Dioxazoline 1,3-PBO
Dioxazoline(1,3-PBO) is an important intermediate of organic reaction. Compounds containing two carbon, nitrogen, oxygen and carbon-nitrogen double bonds with five membered het-erocycles, because their chemical properties are quite active, can carry out ring opening reactions with carboxyl, acid anhydride, amino, epoxy, cyano, phenolic hydroxyl, isocya nate, etc. at a certain temperature, so dioxazoline can often be used as chain extender or crosslinking agent for polymers
Product Characteristics of Dioxazoline 1,3-PBO
1. Strong chemical activity
2. Fast reaction time
3. No small molecules were generated in the reaction.
Specification of Dioxazoline 1,3-PBO
| Item | Specification |
| Appearance | White powder |
| Purity | ≥99.0% |
| Melting point | 143~146 ℃ |
| Volatiles | ≤0.5% |
| Ash | ≤0.1% |
Applications of Dioxazoline 1,3-PBO
Dioxazoline(1,3-PBO) 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.
Package and Storage of Dioxazoline 1,3-PBO
25kg/drum or 20kg/carton,
Tightly sealed, room temperature, keep dry and well ventilated
