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 manufactured using either ethyl acetate or a cyclohexane–ethyl acetate cosolvent mixture....
The product is polymerized by solution polymerization method, using acrylic acid as raw material, under the action of initiator. The polymerization of acrylic acid is fast and exothermic. In order to control the polymerization process, acrylic acid is usually mixed into an aqueous solution of less...
Acrylic, any of a broad array of synthetic resins and fibres that are based on derivatives of acrylic and methacrylic acid. Both acrylic acid (CH2=CHCO2H) and methacrylic acid (CH2=C[CH3]CO2H) have been synthesized since the mid-19th century, but the pra
conducted simulations and designed proposed model using commercial simulators that referred as the patent product components. This process introduced a quencher using solvent to cool the main stream in order to separate water in extractor unit and to avoid acrylic acid polymerization. It remove water ...

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 ...
[5]. It is corrosive to metals and tissue and prolonged exposure to fire or heat can cause polymerization. If polymerization takes place in a closed container, violent rupture may occur because the polymerizaiton of acrylic acid is exothermic. The inhibitor (usually hydroquinone) can greatly ...
