AD1, 4 – CHDA also can make the resin a good balance between hardness and flexibility, 1, 4 –
CHDA can be used to improve the dispersion of acrylic resin, as well as with good storage
stability.In addition, 1, 4-CHDA coordinated with acrylic resin better than resorcinic acid
(DOP).The reactivity of 1, 4-CHDA was higher than PIA
In medicine, used in the synthesis of peptic ulcer drugs; in polyester resin, used as a modified
monomer to improve the yellowing of polyester resin and its flexibility (softness) without
changing its hardness.
