Effect of alkyl group substituents on the thermal and enzymatic degradation of poly (n-alkyl acrylates)
Effect of alkyl group substituents on the thermal and enzymatic degradation of poly (n-alkyl acrylates) J. P. Mahalik and Giridhar Madras∗ Department of Chemical Engineering, Indian Institute of Science, Bangalore-12 Abstract The effect of alkyl group substituents on the thermal degradation kinetics of poly (n-alkyl acrylate) was investigated in pyrolysis and in solution. The activation energie...
متن کاملPolymerization of Alkyl Acrylates and Alkyl Methacrylates with Starch
A series of C4-C 12 alkyl acrylates and methacrylates was polymerized with starch by irradiating starch-monomer mixtures with 60CO. Homopolymers were extracted with cyclohexane. The amounts of insoluble versus soluble synthetic polymer in polymerizations run with alkyl acrylates varied less with the chain length of the alkyl substituent than in the polymerizations run with alkyl methacrylates: ...
متن کاملApplication of Triphenylphosphine for Facile Synthesis of Several Alkyl Acrylates from Heterocyclic Phenols
7-Hydroxycoumarine undergoes a smooth reaction with alkyl propiolates in the presence of triphenylphosphine (15 mol%) to produce the corresponding alkyl (E)-3-((2-oxo-2H-chromen- 7-yl)oxy)acrylate in good yields. When the reaction was performed by 3-hydroxyquinoline similar alkyl acrylates were obtained.
متن کاملComputational study of chain transfer to monomer reactions in high-temperature polymerization of alkyl acrylates.
This article presents a computational study of chain transfer to monomer (CTM) reactions in self-initiated high-temperature homopolymerization of alkyl acrylates (methyl, ethyl, and n-butyl acrylate). Several mechanisms of CTM are studied. The effects of the length of live polymer chains and the type of monoradical that initiated the live polymer chains on the energy barriers and rate constants...
متن کاملAcrylates.
ACRYLATES HAVE been around since the 1930s, when Rohm and Haas began mass production of Plexiglas, a clear and resistant glass substitute made of polymerized methacrylate. It is used extensively for windowpanes, airplane canopies, car lights and windshields, streetlamps, and so on. Numerous other acrylates have been synthesized and have found applications in paints and adhesives, dental composi...
