Summary Copolymers of soybean vinyl ether with each of six low alkyl vinyl ethers have been investigated in the infrared. The ether band in the 1100 cm −1 region has been found useful in determining the composition of copolymers. The composition of copolymers has been determined at a fixed frequency of 1100 cm. −1 and at the absorption maximum in the region of 1100 cm. −1 . Determination may be accomplished with equal success at the absorption maximum in this region if the material being incorporated absorbs at a frequency not too far removed from 1100 cm. −1 . This would be the preferred method if using a recording instrument.
