description Acrylic monomers of the formula in which Y is a hydrogen atom or methyl radical, X is hydrogen, an alkyl group containing 1 to 4 carbon atoms, , , , , , , -R1-Z, -R1-OH, -R1-CN, -R1-SH, -R1-OH, -R1-SR, -R1-NHR, -R1-NRR, R1 being an alkylene group with 2 to 4 carbon atoms, Z is a halogen atom, R is an alkyl group with 1 to 4 carbon atoms, are stabilized by 5 to 5000 p.p.m. of at least one acyclic or alicyclic hydrocarbon containing 7 to 12 carbon atoms and having at least 3 conjugated double bonds. The hydrocarbon may contain minor amounts of other hydrocarbons or other inert compounds. The stabilizer is effective against "popcorn polymerization" during distillation. Numerous examples of acrylic monomers and stabilizers are given.ALSO:Acrylic monomers of the formula in which Y is a hydrogen atom or methyl radical, X is hydrogen, an alkyl group containing 1-4 carbon atoms, , , , , , , , , , , , R1 being an alkylene group with 2-4 carbon atoms, Z is a halogen atom, R is an alkyl group with 1-4 carbon atoms, are stabilized during distillation by adding 5-5000 p.p.m. of at least one acyclic or alicyclic hydrocarbon containing 7-12 carbon atoms and having at least 3 conjugated double bonds. The hydrocarbon may contain minor amounts of other hydrocarbons or inert compounds. Numerous examples of acrylic monomers and stabilizers are given.
