Recently various types of rapid mold heating/cooling technology have been developed in order to improve surface quality of products and flow ability of polymer. In this study, injection molding CAE for rapid mold heating and cooling was performed to analyze molding characteristics of the automobile band-cable. The effects of the rapid mold heating and cooling technology on the molding characteristics and pressure distribution were compared with conventional injection molding. Finally, we evaluated component technologies such as rapid mold heating and cooling system, mold materials, vacuum system through experiments to solve molding problems.

There have been significant developments in the pillaring of lamellar ionic materials, and the resulting zeolite-like pillared derivatives have built a large family of microporous materials. The intercalation of cubic octomer derived from the controlled hydrolysis of 3-amino propyltriethoxysilane with smectite clays has been studied. The organosilicon are adsorbedd in amounts exceeding the cation exchange capacity of mineral. The excess quantityis incorporated in the form of pysically adsorbed ion pairs [(H₃N-Pr)_8O_(12)Si_8](OH)_8.

Poly(acrylic acid)/Na-MMT superabsorbent nanocomposite was synthesized. Acrylic acid(AA) used as a monomer, N,N'-methylenebis-acrylamide was used as a crosslinker, and potassium persulfate was used as an initiator. Absorption amount of water at the superabsorbent nanocomposite was 311 to 801 times of' superabsorbent nanocomposite weight. Superabsorbent nanocomposite with a water absorbency higher than 801g H_2O/g was synthesized having 0.10 wt% crosslinker, 1.8 wt% initiator, 10 wt % Na-MMT, a neutralization degree of 65 % and a reaction temperature of 70℃.
