formal filter ! Polyacrylamide made in China

polyacrylamide :
widely used in thickening,
colloidal stability, drag reduction, bond,
film, biomedical materials, etc.
Polyacrylamide

1,
physical properties:
The physical properties of polyacrylamide mainly depends on the
behaviour in aqueous solution. Because of molecules chain gene
containing amide groups or ions gene, the distinguishing feature is
highly
hydrophilic,
and it
can be dissolved
in water in various proportions, and
polyacrylamide aqueous solution on the electrolyte has a
good tolerance
,
such as it is not sensitive with ammonium chloride, sodium sulfate, ,
and compatible.with surface active agents.

2,
Chemical reaction:
The pendant group of polyacrylamide chains is
lively acylamino
, chemical
reactions can occur on a variety of derivatives can be obtained, but for the
effect of neighboring genes, the reaction often can not be fully carried out.
