The aspartic acid which possesses the biodegradation characteristic which is improved manufacturing method and its use of condensation polymerization ones

摘要

(57) Abstract Any condensation polymerization where the aspartic acid which possesses the biodegradation characteristic which is improved as for manufacturing method of condensation polymerization ones, minute aspartic acid, with the solid phase, at temperature of 180 - the 25 the quantity which the water which is formed with process of condensation polymerization heat by condensation polymerization, the possible quantity does not exceed 70 weight % theoretically until it is removed, consists of the fact that it makes condense heavily from this reaction blend, is obtained things are useful as a detergent and a cleaner additive, at the same time as a scale inhibiter.
