In an alternative embodiment, a textile processing or cleansing compound is included in the polymerization reaction along with the acrylic acid and aromatic sulfonic acid or its salt. The resulting polymers have superior properties for use in textile processing and cleaning, and can be used as ...
Poly (acrylic acid) is synthesized in water-borne system via radical polymerization reaction using potassium persulfate and sodium pyrosulfate as initiator and iron (II) sulfate pentahydrate as chain length regulator. Solubility Poly (acrylic acid) is soluble in water, alkali water, alcohols, formamid...
While oxygen functions as an inhibitor in acrylic acid polymerizations, MEHQ was shown to function as a retarder. The decrease in the rate of polymerization allowed the calculation of an inhibition constant for this system. MEHQ was found to remain in the polymerizing mixture throughout the ...
The polymerization reaction was performed in tetrahydrofuran (THF) using azobisisobutyronitrile (AIBN) as initiator. The initial molar ratio is varied (as shown in Table 5.1) in order to fine-tune the final composition of the copolymer and consequently its final properties. After purification, the ...
In particular, the proportion of the hypophosphorous acid (salt) added before the polymerization reaction is preferably 2 to 80 mol % based on 100 mol % of the total amount of the hypophosphorous acid (salts) to be used. The proportion thereof is more preferably 5 to 60 mol %, and still...
Monte Carlo Simulation of Solid Phase Graft Polymerization of Acrylic Acid onto Polypropylene By assuming that a reaction is mainly a single-radical chain termination, the mechanism, for solid-phase radical graft polymerization of acrylic acid (AA) ... ZH Luo,J Li,XL Zhan,... - 《Journal of...
The metered acrylic acid (AA) monomer is mixed with a certain amount of water and placed in another drip funnel on the polymerization reactor. When the water temperature in the reactor reaches the temperature required for the reaction, the acrylic monomer aqueous solution and the initiator ...
-acetylaminoacrylic acid was kinetically investigated in dimethylsulfoxide (DMSO) and aqueous DMSO. The polymerization conforms to a conventional radical equation (rule of square root), independently of pH. However, the polymerization rate is greatly dependent on pH: The rate decreases with pH increas...
Carbomers are synthetic, high-molecular-weight, crosslinked polymers of acrylic acid. These acrylic acid polymers are crosslinked with allyl sucrose or allyl pentaerythritol. The polymerization solvent used previously was benzene; however, some of the newer commercially available grades of carbomer are ma...
Poly(acrylic acid)-g-poly(alkyl methacrylate) amphiphilic graft copolymers with narrow mo- lecular weight distributions were synthesized by atom transfer radical polymerization (ATRP) and grafting-from main-chain technique. The well-defined products were characterized by FT-IR, 1H NMR and gel permeat...
