PENTAERYTHRITOL TRIALLYL ETHER Application Usage:
1: Crosslinking Agent
CAS 1471-17-6 Its three reactive allyl ether groups enable it to function as a crosslinking monomer in thermosetting resins, forming dense, three-dimensional polymer networks that significantly enhance thermal and chemical resistance.
2: Polymer Modifier
It acts as a property modifier in polymers like polyurethanes and elastomers by introducing pendant allyl groups, which provide additional sites for curing to improve mechanical strength, flexibility, and aging stability.
3: Photocuring Component
It serves as an efficient, low-viscosity reactive diluent and co-monomer in UV-curable coatings and inks, where its allyl ether groups undergo rapid free-radical polymerization under light exposure to form hardened films with minimal shrinkage.
Chemical properties
Pentaerythritol triallyl ether (PTAE, CAS 1471-17-6) is a colorless-to-pale-yellow liquid with a neopentyl backbone bearing three allyl ether groups (enabling free-radical crosslinking with unsaturated polymers via peroxide/UV initiation) and one primary hydroxyl group (supporting esterification/urethane formation), featuring high thermal stability (boiling point 156–161 °C at 3 mmHg), low viscosity (20 ± 10 mPa·s at 23 °C), solubility in organic solvents (alcohols/ethers/esters) but not water, and peroxide formation upon air/light exposure—all properties rooted in its molecular structure and validated by polymer chemistry principles and physical characterization data.
