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.

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.

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.

Research on performance of polymer modified asphalt

The low temperature force-ductility performances of SBS,SBR,EVA,PE polymer modified asphalts were studied by force-ductility tests.

Introduced in this article are the unconventional methods of testing the polymer modified asphalt which is widely used in current China.

The formation and development of interfacial transition zone (ITZ) in polymer modified mortar (PMM) were studied by means of the alternating current impedance spectroscopy (ACIS).

Polymer modified mortar is a new trend of cement-based mortars.

Electrical conductivity of polymer-modified mortars (PMM) with different volume fractions of sand was measured using an alternating current impedance spectroscopy.
