Trimethylolpropane Diallyl Ether (TMPDE) contains both trimethylolpropane and diallyl ether functional groups, which contribute to its reactivity and versatility in various chemical reactions.
It is soluble in organic solvents but insoluble in water, also can be synthesized through the reaction of trimethylolpropane with allyl chloride or allyl alcohol.

Unsaturated Polyester Resins
As a Drying Agent:
1)TMPDE is used as an excellent resin air - drying agent. In unsaturated polyester resins, it significantly accelerates the surface - drying speed. When the resin is applied, for example, in coating applications or in the production of composite materials, the presence of TMPDE helps the resin to dry more quickly on the surface. This is crucial in applications where a fast - drying surface is required to prevent dust or other contaminants from adhering to the resin.
2)It also enhances the hardness of the resin. The cross - linking reactions that TMPDE participates in lead to a more rigid and durable resin structure. This increased hardness makes the resin more suitable for applications where mechanical strength and resistance to abrasion are important. For example, in the production of fiberglass - reinforced polyester products, the hardened resin provides better protection to the underlying fiberglass and also allows for easier sanding and finishing operations.
Reactivity in Esterification:
TMPDE contains one hydroxyl group and two allyl groups. In the esterification reaction, the hydroxyl group can react with carboxyl groups. This reaction is an important part of the resin - forming process. The reaction between TMPDE and carboxylic acids (or acid anhydrides) helps to incorporate TMPDE into the polyester resin structure. The allyl groups can also participate in other polymerization or cross - linking reactions, further modifying the resin's properties and improving its performance. For example, in the polymerization of unsaturated polyester resins, the allyl groups can undergo free - radical polymerization reactions, which contribute to the formation of a more complex and stable resin network.
