Glycidal ethers

Only a few commercial uses for TDA per se have been found. In epoxy curing appHcations, 2,4- I DA has been used as a component of a eutectic mixture with short chain aUphatic glycidal ether resins (46) as well as by itself (46,47) TDA (46) and single isomers (47) are also used as amine curatives. TDA can be used as a chain extender in polyurethanes (48,49). TDA is cited as a monomer in making aromatic polymers with unique properties, eg, amorphous polyamides (50), powdered polyamides (51), and low melting, whoUy aromatic polyamides (52). 

Reaction of epichlorohydrin with I-naphthol affords the glycidic ether (61). Opening of the oxirane ring with isopropyl-iimine gives racemic propranolol (62) the only 3-blocker... 

A mixture of 16.3 g of (2-chloro-5-methylphenyl)glycidic ether (from epichlorohydrin and 2-chloro-5-methylphenol) and 6.2 g of t-butylamine in 50 ml of ethanol is heated at reflux for 6 hours. The solvent is removed, the residue Is washed with water and then extracted with benzene. The dried extract is evaporated to give 1-t-butylamino-3-(2-chloro-5-methylphen-oxy)-2-propanol. Treatment of the free base in benzene solution with dry hydrogen chloride yields the hydrochloride salt.

Only emulsion and suspension polymerization of VDF are commercially practiced because water provides a sufficient heat sink for the large heat release associated with VDF polymerization. Only one VDF-copolymer with nonfluorinated comonomers, maleic monoesters, and allyl glycidal ethers has been commercialized for battery applications (18) all other reported VDF-copolymers with nonfluorinated oleflns have been laboratory or patent examples (3).

The mechanical properties of propylene oxide rubbers (copolymers of propylene oxide and allyl glycidal ether) depend both on the catalyst used in preparing the polymer and on the comonomer content. The mechanical properties are very much influenced by the ability of propylene oxide stereosequences in the copolymer to crystallize. The crystalline material can give a substantial Increase in modulus and in the strength of the polymer on stretching.
