The emulsion polymerization of vinyl acetate possesses the rather typical properties in comparison the emulsion polymerizations of the comonomers.
Polymerization vinyl acetate.
In the present report the madix polymerization of vinyl acetate in bulk or solution polymerization dichloromethane dcm or ethyl acetate was investigated in order to optimize monomer conversion and achieve molecular weight control.
Therefore vinyl acetate runaway polymerization incidents are very serious and they occur with a high frequency.
Polyvinyl acetate is prepared by the polymerization of vinyl acetate monomer free radical vinyl polymerization of the monomer vinyl acetate.
Applications edit as an emulsion in water pvac emulsions are used as adhesives for porous materials particularly for wood paper and cloth and as a consolidant for porous building stone in.
Reacts with air or water to produces peroxides that initiate explosively violent polymerization.
Thus the type of emulsion polymerization process batch semi continuous or.
The controlled polymerization was photoresponsive.
The polymerization of vinyl acetate is probably the second most frequent cause of runaway reaction accidents in the chemical industry after the phenol formaldehyde runaway reaction.
Vinyl acetate has high water solubility a high monomer polymer swelling ratio and a high chain transfer constant.
Since vinyl alcohol is highly unstable with respect to acetaldehyde the preparation of vinyl acetate is more complex than the synthesis of other acetate esters.
It is a nonstructural adhesive with low price convenient usage and wide application range.
