Experimental and theoretical approaches for structural and mechanical properties of novel side chain LCP-PP graft coproducts
The monomers p-biphenyloxycarbonylphenyl acrylate (BPCPA) and p-biphenyloxycarbonylphenyl methacrylate (BPCPMA) were synthesized by the reaction of p-acryloyloxybenzoyl chloride and p-methacryloyloxybenzoyl chloride with 4-hydroxybiphenyl, respectively, a
A method of manufacturing a carboxylic acid monomer
PROBLEM TO BE SOLVED: To provide a method for producing a carboxylic acid monomer with a slight halide content by using an easily available carboxylic acid compound and (meth)acrylic anhydride as raw materials. SOLUTION: A carboxylic acid monomer such as 2-(methacryloyloxy)acetic acid, 2-(methacryloyloxy)propionic acid or 2-(methacryloyloxy)-2-phenylacetic acid is produced by reaction between the corresponding carboxylic acid compound having OH, SH or NH2group and (meth)acrylic anhydride. In this case, an OH-bearing carboxylic acid compound to be used is preferable as a raw material. COPYRIGHT: (C)2012,JPOandINPIT

Immobilized thermolysin and synthesis of precursor of aspartame
The optimal condition of the thermolysin-catalysed condensation reaction of N-benzyloxycarbonyl-DL-aspartic acid (Z-DL-Asp) with DL-phenylalanine methyl ester (DL-Phe-OMe) giving N-benzyloxycarbonyl-L-aspartyl-L-phenylalanine methyl ester, the precursor of the synthetic sweetener (aspartame, APM) has been investigated.The immobilized thermolysins have been prepared using seven polymethacrylate derivatives as carrier by covalent coupling of the polymers with enzyme.Seven derivatives have been synthesized using methacrylic acid, p-hydroxybenzoic acid and thecorresponding activated amide or amine.The abilities of the immobilized thermolysis to catalyze the condensation reaction have been tested and 100percent yield has been obtained by using one of them.
