Acrylamide and polyvinyl alcohol copolymers of acrylic acids are active to uptake metal ions and use for removal or preconcentration of metal ions .
Summary: Acrylic acid was polymerized and modified with some acids such as salicylic acid, benzalthiobarbituric acid and some amines such as aniline and [alpha]-naphthylamine.

Looking at raw materials, BCF reports ethyl acetates prices are up over 20%, acrylic resins were up 5% in 2004 and 7% in 2005 so far, 20% for acrylic acids
and acetates, 32% for ethylene, and UV resins up 10%.
Crisp and Wilson (1977) reasoned that copolymers of acrylic acids would be less regular than simple poly acrylic acid and so less liable to form intermolecular hydrogen bonds.
Glass ionomer cement composed of a calcium--alumino--silicate glass powder and an aqueous solution of an acrylic acid homo--or copolymer.
DGER may be used as is, or reacted with other compounds such as acrylic acids
. DGER is non-toxic.
The company is also currently working on a deal with Brazilian-based chemical company Petrobras to produce acrylic monomers, acrylic acids
and super-absorbents for the diaper and feminine hygiene markets.
In this work, different poly(butadiene-co-acrylic acid(g)acrylic acid) and poly(butadiene(g)acrylic acid) polymers were obtained by reaction of oligomers and acrylic acids in different ratios and conditions.
All these substrates were prepared by using a co-oligomer (butadiene-co-acrylic acid) synthesized by copolymerization in a closed steel reactor at 70[degrees]C using 1,3-butadiene and acrylic acid as monomers and benzoyl peroxide as initiator.
The surfactants are selected from a group consisting of cross-linked polyoxyethylene acrylic acids
, fatty alcohol polyglycol ethers, polyvinylpyrrolidone, alkyl ethoxylates, alcohol alkoxylates, alkylpheno polyglycol ethers, lignin sulfonates, naphthalene sulfonic acid derivatives and mixtures thereof.
