Research on electrospinning of nanofibers from natural polymers;

This paper discusses the degradation principle and way of ecological super absorbent polymers by its chemical structure,induces the studies on degradation natural polymer,graft copolymerization of acrylic acid and acrylic acid(salt) polymer.

Chitosan,collagen and gelatin are important natural polymer materials in tissue engineering field.

And the technical methods of preparation and application of high performance mortar by Point-DGN high performance mortar additive through low-dosage(1～3%) polymer modification were discussed also.

Among these areas,the applications in polymer modification have become research focus at home and abroad in recent years.

Here the general application of MMA(methyl methacrylate) in polymer concrete is told,the conditions for the use of the polymer are explained and some suggestions for the polymer modification are given.

During wash and wear finish of pure cotton fabric,the water soluble low molecule modified polymer Serirez AP-ZF was used to increase the crease resistance,ensure the strength and reduce the water shrinkage of finished fabric without free formaldehyde.

Experiment on crack resistance and impermeability of polymer modified mortar;

The author discuss the mechanism of modifying effects of organic compound on cement,and point out that the polymer modified composite should be improved further to provide greater variety,high strengthed and controllable setting time.
