摘要

Polyacrylamide(PAAm) of high molecular weight has widely been used in many fields, i.e. oil recovery, papaer industry, dispose of waste water etc.. However, there are still some problems in preparing and using super high molecular weight PAAm. One of the key problem is that the dried polymer was very difficult to be redissolved and the practical use was limited. This may be caused by the hydrogen bonds between PAAm chains or the crosslingkage formation. N-Acrylyl-morpholine(AMP) is a derivative of acrylamide, with no hydrogen atom attached to N atom, thus the hydrogen bond or cross-linking formation of its polymer may be greatly reduced, super high molecular weight PAMP with good properties may thus be obtained. In this paper, N-methacrylyl-N'-pyrimidinopiperazine (MPMP) and potassium sulfate (KPS) redox system was used as an initiation system for the reverse suspension polymerization of AMP in water[1-3].
