| Formula: C3H4O2 CAS: 79-10-7 Description: Acrylic acid glacial is a colorless liquid having a sharp, acrid odor. It is completely soluble in water. Acrylic acid is a monomer used in industrial synthesis and for producing polymers Applications: Acrylic acid is a versatile a, ß-unsaturated carboxylic acid. It can enter into common reactions with a large number of organic and inorganic compounds and intermediates for the synthesis of many low and high-molecular weight compounds. Some typical reactions/applications include:- As a vinyl compound in addition reactions.
- As a carboxylic acid — acrylic esters, acrylamide, N-substitute amides and acrylic acid chloride.
- Copolymers with acrylic esters, methacrylic esters, acrylonitrite maleic acid esters, vinyl acetate, vinyl chloride, vinylidene chloride, styrene, butadiene and ethylene.
- Homopolymers of acrylic acid and copolymers form water-soluble compounds in acid form or their alkali/ammonium salts. Uses include thickening agents; dispersing agents; protective colloids for stabilizing emulsions and polymer dispersions wetting agents. AAG is used to produce very high molecular weight polymers for flocculents and viscosity control in oil-well drilling mud.
- Superabsorbant polymers are lightly crosslinked polyacrylic acid salts.They are used for fluid retention, largely in baby diapers, but also in products for feminine hygeine, adult incontinence and agriculture.
- Copolymers with less than 50% acrylic acid produce polymers only slightly soluble or even insoluble in water. Their alkali or ammonium salts are used in sizes, adhesive intermediates, and binders for printing inks and coatings.
- Copolymers with small amounts of acrylic acid improve adhesions and improve resistance to oil and solvents.
In polymer dispersions, acrylic acid addition improves stability and compatibility with pigments.Information provided by BASF |
