Methyl Vinyl Ketone Polymerization

The highest order recorded is 7 4.

Methyl vinyl ketone polymerization.

The photo polymerization of methyl vinyl ketone vapour at pressures up to 60 mm. Up to 1 hydroquinone may be added as a polymerization inhibitor. This polymerization may cause violent ruptures in containers. 455 btu lb 253 cal g 10 6 x 105 j kg 9 17 heat of fusion.

Methyl vinyl ketone mvk iupac name. Methyl vinyl ketone is incompatible with strong oxidizers and strong bases. And temperatures between 0 and 60 degrees c has been investigated with the following results. The temperature coefficient of the reaction is negative but the rate does not.

The vinyl carbonate 13152 gives only copolymerization the ketene acetal 11153 and the methyl vinyl ether 14152 give both copolymerization and chain transfer in styrene polymerization whereas with the benzyl vinyl ethers 12 153 15 8 and 16 18 151 chain transfer is the only reaction detected. Abstract this article describes the copolymerization of methyl vinyl ketone mvk methyl acrylate ma and methyl methacrylate mma with styrene st as reference monomer at 3 4 mpa and 335 k with toluene as solvent. The kinetic order of the reaction increases with pressure and decreases with increasing tem perature. It is a colorless flammable highly toxic liquid with a pungent odor.

The temperature coefficient of the reaction is negative but the rate does not obey the. Methyl vinyl ketone is available in a grade of 98 5 purity. The polymerization of methyl vinyl ketone in the presence of sodium t butoxide takes place through the anion tert buo ch2 h c o j ch3 the polymer formed structure i then undergoes cycliza tion where the anion initiator itself probably acts as the base in the hydrogen transfer process. B ketones are hydrocarbons with the general structural formula of r co.

The photo polymerization of methyl vinyl ketone vapour at pressures up to 60 mm. The polymerization of methyl vinyl ketone with these metal alkyl catalysts was found to be anionic in nature from a series of copolymerization experiments phenyl vinyl ketone and methyl isopropenyl. And temperatures between 0 and 600 c has been investigated with the following results. It is soluble in water and polar organic solvents.

9 19 reid vapor pressure. The highest order recorded is 7 cdot 4. It polymerizes spontaneously upon exposure to heat or sunlight. In addition the effect of pressure on the binary copolymerizations of st ma mma is discussed.
