Polymerizable monomers from castor oil. I. Vinyl monomers based on undecenoic acid

Thirty‐four different vinyl monomers have been synthesized, based on 10‐undecenoic acid, pyrolysis product of castor oil, in 50 to 100‐g lots in high purity. These include allyl ethers and esters, vinyl ethers and esters, and acrylic and methacrylic esters, all of which were characterized by their infrared spectra; purity was checked by chromatographic methods. Boiling points, refractive indices, and iodine values of the products have been reported.
