The effect of β nucleating agent on the crystalline property of polypropylene(PP)is investigated.

Synthesis and characterization of crystallized & cross-linked high water vapor permeable polyurethane;

And then the solution of salt has condensed and crystallized.

The technical process as follows:deliquate brine—dissolve mineral-adjust concentration—cultivate—crystallize—separate—mirahilite.

The cohesive energy desity,viscosity and viscosity average molecular weight plus crystallinity of aramid paper before and after heat-calendering were determined.

In this paper, based on the x-ray diffraction experiment, the crystallinity,preferred orientation and mechanics behavior of PSA fiber after thermal treating were discussed in detail.

In order to control the crystallinity of the hard and soft segments,1,2-PG and PNA,which contain(dissymmetrical) and symmetrical side methyl groups respectively,were incorporated into the hard-segment and the soft-(segment) respectively.
