The preparation of profile control agent having swellable particles from oily sludge for water plugging and profile control was a new measure of sludge treatment and utilization.

The technology of bulky top produced by dry spinning acrylic tow is introduced.

Application performance of dry spinning of acrylic tow which is produced for bulky top by tow to sliver convertion system domestic and abroad is analysised by the same equipments,as a result,dry spinning of acrylic tow of 6.

Synthesis and behavior evaluation of water-blocking agent with temperature-resist and salt-tolerant swellable particle;

The high salt-tolerant swellable particles were synthesized by means of aqueous solution pol- ymerization.

Development of high shrinkage acrylon/viscose bulked yarn for knitting;
