Abstract
549,234. Chemical testing. NORTON GRINDING WHEEL CO., Ltd. Oct. 7, 1940, No. 14972. Convention date, Oct. 6, 1939. Drawings to Specification. [Class 1 (i)] [Also in Group IV] The unsaturated monomeric methylene compounds specified below are exposed to air or oxygen to form therein a small proportion of the peroxide of the compound to act as a catalyst in the subsequent polymerization of the monomer. The concentration of the peroxide in the monomer may be determined by a colorimetric test, the yellow colour of iodine liberated from a freshly prepared solution of potassium iodide in water being compared either with the colour of iodine liberated from a similar solution by the addition of a known amount of peroxide, or with standards prepared by diluting aqueous solutions of potassium dichromate to match the colour of iodine liberated by a solution of peroxide of known concentration. The unsaturated monomeric compounds specified are (1) vinyl esters of lower aliphatic acids, (2) acrylic and methyl acrylic acids and their lower alkyl esters, (3) substituted ethylenes, (4) ketones containing the unsaturated methylene group, (5) aldehydes, (6) mixed anhydrides such as acrylic and methacrylic formic anhydride, (7) vinyl, isopropene, allyl and methallyl esters of methacrylic acid, (8) polyhydric alcohol (including the hypothetical ethylidine glycol) esters of acrylic and methacrylic acids, (9) divinyl ketone and alpha substituted divinyl ketones, and (10) interpolymers of mixtures of the monomers specified above.
