Vinyl Ether Acrylic Acid

A vinyl ether group containing meth acrylic ester composition which comprises a radical polymerization inhibitor and a vinyl ether group containing meth acrylic ester represented by the following general formula 1.

Vinyl ether acrylic acid.

Dissolved oxygen is also an strong inhibitor and its presence in the solution enhances the inhibition effects of mehq. Acrylic elastomer can generally be characterized as one of two types. Even traces of. In this work we developed a comprehensive mathematic model for the inhibition of acrylic.

Vinyl ethers undergo homopolymerization via a cationic mechanism. Vinyl ethers undergo radical initiated copolymerization in the presence of specific monomers such as maleates fumarates and acrylics. Ch2 cr1 coo r2 0 ch ch r3 1 in the formula r1 represents a hydrogen atom or a methyl group r2 represents an organic. Inhibitors such as mehq monomethyl ether hydroquinone and ptz phenothiazine are added to acrylic acid in the shipping and storage process to prevent its spontaneous polymerization.

This colorless liquid has a characteristic acrid or tart smell. It is the simplest unsaturated carboxylic acid consisting of a vinyl group connected directly to a carboxylic acid terminus. Phosphate buffer solution pbs of ph 7 4 was used as swelling medium in order to determine the temperature. 21 the vinyl ether transfer agents like other vinyl ethers generally show marked acid sensitivity and are not suited for use with acidic monomers e g acrylic acid aa methacrylic acid maa.

They are increasingly used in radiation curing systems because of a lower toxicity profile than the commonly used acrylic monomers. Old types include acm copolymer of acrylic acid ester and 2 chloroethyl vinyl ether containing chlorine and anm copolymer of acrylic acid ester and acrylonitrile without chloride. Propenoic acid is an organic compound with the formula ch 2 chcooh. The polymers and corresponding monomers listed are available from us.

New types do not contain chlorine and are less prone to mold related staining. It is miscible with water alcohols ethers and chloroform more than a million tons are produced annually. Comonomers ethylene glycol vinyl ether egve butyl vinyl ether bve acrylic acid aa and crosslinking agent diethylene glycol divinyl ether degdve were obtained from aldrich germany and they were used without purification.
