1. Characteristic defects are of two main types; regression and syneresis.

2. Syneresis of gel under certain conditions is the inherent behavior of gel. Slight syneresis has no effect on the application of gel in the porous media.

3. The salinity has no effect on the syneresis of xanthan - chromium ( III ) gel system.

4. The syneresis is considered to originate from some condensation reactions of hydratable reactive groups in the crosslinked polymer networks.

5. The results showed that the product had high viscosity, constant viscosity, water - absorption capacity and good anti - syneresis.

6. The prediction results of syneresis are given when the volumes of gel reach50 %, 20 %and10 %of its original volume.

7. The application of complex konjac gum in jelly processing were investigated. It was observed that the konjac gum decreased the syneresis rate of jelly.

8. The performances of three kinds of gels were compared by the experiments of viscosity, gel intensity, syneresis rate, adhesive power, gel freezing point as well as melting point and so on.

9. The present invention relates to a latex composition for dip molding comprising a carboxylic acid modified nitrile-based copolymer latex and starch, and a molded product produced thereby, and provides a dip molded product having slow syneresis, low stickiness, and excellent tensile strength by mixing and using a carboxylic acid modified nitrile-based copolymer latex and starch.
