Preparation and Enzymatic Hydrolysis of Polymers Anchoring Biphenyl-2-ol
Ishikawa, Tomomichi,Tanaka, Youji
, p. 1182 - 1185 (1985)
Polymers anchoring fungicidal biphenyl-2-ol(BPOL) were prepared by the polymerization and copolymerization of 2-biphenylyl methacrylate(BPMA) with various comonomers such as styrene, vinyl acetate, 2-hydroxyethyl methacrylate, N-methacryloylglycine, and N-methacryloyl-DL-alanine.The reactivity ratios of BPMA with the comonomers were evaluated.The α-chymotrypsin-catalyzed hydrolysis of the polymers was also studied.The release of BPOL from the polymers was represented by means of the Michaelis constant Km and the catalytic-rate constant kcat.The BPMA homopolymer gave higher Km and kcat values than the copolymers, and the copoly mers with a higher content of substrate units underwent cleavage more readily.It was found that the hydrolysis of the polymeric substrates is affected by the structure and character of the comonomer rather than the arrangement order of the repeating monomer units in the polymer sequence.

Paragraph 0019; 0020; 0023, (2018/12/05)
PROBLEM TO BE SOLVED: To provide a production method for obtaining (meth) acrylate in high yields, by preventing a large amount of waste from produced from by-products, like the conventional art. SOLUTION: A method for producing (meth) acrylate includes the reaction between a compound represented by the following formula (I) and an aryl alcohol. Preferably, the reaction occurs in the presence of a catalyst of at least one metal compound selected from first Group metal compounds and second Group metal compounds.
