g, by swelling properties of the vulcanizates after elongation, Lorenz-Parks Equation and by Kraus Formula.

A study was made on the influence of length of nylon and polyester fibres on the physical and swelling properties of nylon/NR and polyester/CR composites.

In this thesis, the physical and heat-aging properties of chlorinatedcis-1, 4-polybutadiene composite were mainly studied, and the swelling properties ofthe composite were also studied.

Based on the above,the authors discussed the relation between the montmorillonite content,the exchangeable cationic type between layer and its amount,the montmorillonite structure and the swelling performance of bentonite.

Discussing the corrlelation between the montmorillonite content, the layer ion - exchange type and amount, the montmorillonite structure with swelling performance of bentonite.

The swelling performance of many kinds of "O" -type rubber sealing collar made by different material in biodiesel or mixed diesel were studied,and compared with those in 0# diesel.

The effect of various reaction parameters on the swelling property was investigated systematically, such as the concentration of the monomer, the content of the initiator, reaction time and temperature, as well as intercalation with montmorillonite(MMT).

Their swelling property and separation property for biomacromolecules were studied.

The effect on the sintering and expanding property of haydite shale;

With increasing the amount of waterabsorbent resin, the tensile strength of CPE/P (AAAMHMA) decreased, the equilibriumswelling ratio increased.

The results indicate that the tensile strength of CPE/P(AA AM) decreases, the equilibrium swelling ratio increases with increasing the amount of water absorbent resin.

The effect of reaction parameters,such as the amount of initiator,crosslinker,AA and AM as well as reaction temperature/time on the swelling behavior and responsive properties of the hydrogel was investigated.
