Acrylic acid, polymer

CHi=CMeCOOH. Colourless prisms m.p. 15-16 C, b.p. 160-5 C. Manufactured by treating propanone cyanohydrin with dilute sulphuric acid. Polymerizes when distilled or when heated with hydrochloric acid under pressure, see acrylic acid polymers. Used in the preparation of synthetic acrylate resins the methyl and ethyl esters form important glass-like polymers. 

CHjlCH COOH. Colourless liquid having an odour resembling that of ethanoic acid m.p. 13 C, b.p. I4I°C. Prepared by oxidizing propenal with moist AgO or treating -hy-droxypropionitrile with sulphuric acid. Slowly converted to a resin at ordinary temperatures. Important glass-like resins are now manufactured from methyl acrylate, see acrylic resins. Propenoic acid itself can also be polymerized to important polymers - see acrylic acid polymers.

Polyacrylic acid (pAA) homopolymers and related copolymers have become a commercially important class of water-soluble polymers. Acrylic acid polymers can range in molecular mass from less than 1000 Da to greater than 1,000,000 Da. A representative set of analysis conditions is... 

In nonrigid ionomers, such as elastomers in which the Tg is situated below ambient temperature, even greater changes can be produced in tensile properties by increase of ion content. As one example, it has been found that in K-salts of a block copolymer, based on butyl acrylate and sulfonated polystyrene, both the tensile strength and the toughness show a dramatic increase as the ion content is raised to about 6 mol% [10]. Also, in Zn-salts of a butyl acrylate/acrylic acid polymer, the tensile strength as a function of the acrylic acid content was observed to rise from a low value of about 3 MPa for the acid copolymer to a maximum value of about 15 MPa for the ionomer having acrylic acid content of 5 wt% [II]. Other examples of the influence of ion content on mechanical properties of ionomers are cited in a recent review article [7],... 

A premium antiscalent product in this group is Flocon 100 from Great Lakes Chemical Corporation (originally the brand was owned by Pfizer, then Ciba-Geigy, then FMC). Flocon 100 is a 35% w/w, 2,000 MW acrylic acid polymer. An alternate and much more concentrated product is Good-Rite K-752, a 62.5% w/w, 2,100 MW acrylic acid polymer from Noveon, Inc. (formerly BF Goodrich Company).

Among the gelling agents used are synthetic macromolecules as acrylic acid polymers such as Carbomer 934, cellulose derivatives such as carboxymethyl cellulose or hydroxypropylmethyl cellulose, and natural gums such as xanthan gum. Appendix IV shows the commonly used gelling agents in commercially available pharmaceutical gels.

Xanthates are usually formed by reacting an alcohol or a raw material containing alcoholic hydroxyl groups with an alkali and carbon disulfide (10). However, in the case of the acrylic acid polymer used here, it is not clear how this reaction would proceed. But whatever the mechanism, it appears from the uv spectra and from... 

Emori, Ishizaka, and Koishi. formulated wax matrix tablets for prolonged drug release using a melt-congealing process. They studied the addition of acrylic acid polymer on the release of drug from a wax matrix consisting of carnauba wax and stearyl alcohol in a 1 1 ratio.
