Preparation and adsorption properties of open-cell poly（butylene succinate） foams

Abstract

Abstract: In this study， poly（butylene succinate）（PBS） and ST-CE37B were used as a matrix and an chain extender， respectively， to prepare chain extended PBS samples through melt blending. Furthermore， the open-cell PBS foams were prepared by using a supercritical CO2 foaming method. The results indicated that the addition of chain extender increased the storage modulus of PBS by one order of magnitude and resulted in an increase in its crystallization temperature by 7.69 ℃. When the foaming temperature was 100 ℃ and the foaming pressure was 20 MPa， the open cell content and adsorption capacity for CCl4 of the CPBS foam reached 96.58 % and 31.76 g/g， respectively. Moreover， CCl4 and cyclohexane in water were both removed quickly by the CPBS foam.

Key words: poly（butylene succinate）, chain extension, open-cell foam, high adsorption
