摘要:
A process for producing an aminophosphoric acid-type chelate resin, which comprises aminating halomethyl groups of a polymer having the halomethyl groups on aromatic nuclei, followed by phosphomethylation, wherein the amination reaction is conducted by means of an amine mixture comprising a monoamine and a polyamine, wherein the proportion of the monoamine to the total amount of both amines is from 20 to 70% by mole.
摘要:
A composite separating agent which comprises a hydrophilic polymer separating agent showing a degree of swelling in water of 10 to 100 ml/g-dry and having a giant network structure incorporated within pores of an organic polymer substrate showing a degree of swelling in water of 20 ml/g-dry or below and a degree of crosslinking of 4% to 100% by mol and having a porous structure as well as a process for producing the same are disclosed.When packed within a column, this composite separating agent having a high mechanical strength is hardly compacted and exhibits an excellent separation performance. Thus it is highly useful in chromatographic separation of biopolymers including proteins.
摘要:
Porous cross-linked polyvinyl alcohol particles which is used for a chromatographic medium is prepared by:dispersing an aqueous solution of a mixture of polyvinyl alcohol and a salt in an organic solvent;allowing a gel to form spontaneously from the dispersion; andreacting the gel with a cross-linking agent.
摘要:
An object of the present invention is to provide an electronic apparatus which can imitate a virtual character and in which others than a user can have communication with the virtual character so that the user can enjoy using the electronic apparatus together with the others. Input image information input through an image pickup portion (5) is compared with user's face image data or face feature data stored in a registered dictionary in anon-volatile memory (4), so as to generate response information. The registered dictionary includes partial region image data or feature data of each face part. The response information is generated based on similarity between image information of each face part extracted from the input image information and the registered dictionary. The response information is output to a display portion (6) as information imitating a behavior of the virtual character. Input of image information, comparison with the registered dictionary, generation of response information and output of the response information are controlled by a control portion (1).
