| DIALLYL ISOPHTHALATE Usage And Synthesis |
| Uses | Diallyl isophthalate (DAIP) has the advantage over the ortho isomer that it polymerizes faster and gives polymers of better heat resistance. The DAIP prepolymer is less stable than the diallyl phthalate prepolymer. Cured moldings from DAIP monomer-prepolymer compositions can be better processed than cured diallyl phthalate moldings because of their greater fluidity. Compositions containing DAIP prepolymers can be used for the production of hard, translucent, abrasive-resistant, and laser-trimmable coatings. |
| Preparation | Diallyl isophthalate (DAIP) is prepared by esterification of isophthalic acid with allyl alcohol:
The polymers of diallyl isophthalate are very similar in preparation, properties and application to the polymers of diallyl phthalate described above. Mouldings based on diallyl isophthalate are more expensive but have enhanced thermal stability (withstanding up to about 220??C for long periods) and resistance to organic solvents. |
| Flammability and Explosibility | Not classified |
