Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 1-(tert-Butyl)-1H-pyrrole-2,5-dione, is researched, Molecular C8H11NO2, CAS is 4144-22-3, about Recent advances in photoinduced donor/acceptor copolymerization.Formula: C8H11NO2.
For certain combinations of A and D type monomers, a direct photolysis of the ground state complex or the excitation of the acceptor, followed by the formation of an exciplex, was shown to initiate the copolymerization The main route of initiation of free radical polymerization of donor (D)/acceptor (A) type monomers is based on inter or intra mol. H-abstraction from an excited state maleimide, whereby no exciplex formation takes place. H-abstraction will predominantly take place in systems where easily abstractable hydrogens are present. Laser flash photolysis studies, ESR, and phosphorescence emission studies show that triplet excited states of N-alkyl substituted maleimides (RMI), which are well known strong precursors for direct H-abstractions from aliphatic ethers and secondary alcs., are formed upon excitation. Rates of copolymerization and degrees of conversion for copolymerization of maleimide/vinyl ether pairs in air and nitrogen were measured as a function of hydrogen abstractability of the excited triplet state MI and the influence of concentration and hydrogen donating effect of the hydrogen donor.
Although many compounds look similar to this compound(4144-22-3)Formula: C8H11NO2, numerous studies have shown that this compound(SMILES:O=C(C=C1)N(C(C)(C)C)C1=O), has unique advantages. If you want to know more about similar compounds, you can read my other articles.
