FAQ
Q: Is divinylbenzene mainly used as cross‑linking agent?
A: Yes, its main function is cross‑linking agent.
Q: How does DVB dosage affect resin hardness?
A: Higher dosage increases cross‑link density and hardness, excessive addition causes brittleness.
Q: Could DVB be used for acrylic emulsion polymerization?
A: Yes, it can act as cross‑linking monomer in emulsion copolymerization.
Q: Why is inhibitor added into DVB?
A: DVB has high reactivity, easy self‑polymerization under heat or light; inhibitor prevents self‑polymerization.
Q: Could DVB be applied in 3D‑printing resin?
A: Yes, it improves cross‑link density, solvent resistance and hardness.
Q: Could DVB be used as desorbent?
A: Yes, it is used as desorbent for p‑xylene in industry.
