Vinyl Ether Copolymer

Methyl methacrylate copolymers with vinyl butyl ether as macroinitiators.

Vinyl ether copolymer.

School of chemistry university of st. Methyl vinyl ether is reacted with maleic anhydride to produce the strictly alternating copolymer of various molecular weights in the anhydride form. 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. C 4 h 2 o 3 c 3 h 6 o n.

The anhydride is converted to the acid form by hydrolysis. The anhydrides can also be readily converted into half esters by reacting with alcohols. The material is supplied as a 25 percent aqueous solution and is an excellent film former. Poly methyl vinyl ether alt maleic anhydride 2 product results match criteria.

Copolymerization with acrylates utilizes free radical emulsion techniques. Average m w. Formation of a part of a macromolecule by the mechanism of reversible inhibition. Acrylic elastomer can generally be characterized as one of two types.

Methyl vinyl ether is an organic compound with the chemical formula ch 3 och ch 2 a colorless gas it is the simplest enol ether it is used as a synthetic building block as is the related compound ethyl vinyl ether a liquid at room temperature. Characteristic features of each studied acrylic monomer. Andrews purdie building st. 47 vinyl ether homopolymers are produced by cationic solution polymerization.

Applications poly vinyl ethers and their copolymers find many applications such as adhesives release and surface coatings lubricants greases elastomers anticorrosion agents molding compounds personal care products fiber and textile finishes. Other manufacturers of vinyl ether polymers and copolymers are ashland and idemitsu kosan. Vema family are shown below. Vinyl ether maleic anhydride polymer.

Maleic copolymer linear formula. Maleic anhydride divinyl ether. Poly vinyl ether s 6 or to a lesser degree their copolymers with acrylates for example are frequently used in pressure sensitive adhesive applications.
