The current study reports the complete kinetic anal. of acetoacetoxyethyl methacrylate (AAEMA). The temperature dependent propagation rate coefficient, kp, was accessed by pulsed laser polymerization-size exclusion chromatog. (PLP-SEC), affording the following Arrhenius parameters: A = 2.13 × 106 L mol-1 s-1 and Ea = 19.69 kJ mol-1. For the SEC-anal., the Mark-Houwink-Kuhn-Sakurada (MHKS) parameters of the corresponding polymer were determined (K = 0.0250 mL g-1; α = 0.547) via multiple detection SEC. Furthermore, reactivity ratios for the copolymerization with Me methacrylate (MMA) at 75 °C in Et 3-ethoxypropionate (EEP) were obtained by the Meyer-Lowry method (rMMA = 0.89; rAAEMA = 0.98), supported by a detailed kinetic simulation using the PREDICI simulation package. In addition, copolymerization was carried out at ambient temperature with a bicomponent dibenzoyl peroxide (BPO)/dihydroxyethyl-p-toluidine (DHEPT) initiator system, demonstrating a strong increase of the rate of copolymerization with increasing AAEMA content (i.e. 40% decrease of the gel time by adding 10 mol% of AAEMA). This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9COA of Formula: C7H14O3).
Ethyl 3-ethoxypropanoate (cas: 763-69-9) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.COA of Formula: C7H14O3
