    Abstract: Polystyrene-based composite resin particles includes 100 to 500 parts by weight of a polystyrene-based resin with respect to 100 parts by weight of an ethylene-vinyl acetate copolymer resin. The polystyrene-based composite resin particles are impregnated with a volatile blowing agent and are pre-expanded to obtain pre-expanded particles; the obtained pre-expanded particles are immersed in tetrahydrofuran for 24 hours to obtain an extract A; and the pre-expanded particles are divided into two halves through the center to prepare halved particles, and the halved particles are immersed in tetrahydrofuran for 24 hours to obtain an extract B; and the obtained extract A and extract B are subjected to a GPC (gel permeation chromatography) measurement and obtain the following results: the polystyrene-based resin having a weight-average molecular weight (Mw) of 100,000 to 500,000 gives a peak obtained from chromatograms for the extract A and for the extract B.

    Abstract: The present invention, which is characterized by the employment of blowing agents comprising fluorinated ethers with a boiling point in the range of from about 0 DEG C to 75° C., pertains to a composition of microcellular polyurethane, a method for preparing the same, and its use in manufacturing shoe materials. Compared to shoe soles made from traditional microcellular polyurethane, in particular those made using 1,1,1,2-tetrafluoroethane (HFC 134a) as the blowing agent, the polyurethane shoe soles prepared according to the present invention exhibit similar shrinkage characteristics, and their linear shrinkage is compatible with the current processing conditions, thus can replace traditional blowing systems comprising 1,1,1,2-tetrafluoroethane (HFC 134a) in shoe manufacturing without the need of changing molds. On the premise of being more environmental-friendly, the present invention also effectively saves production cost for shoe manufacturers.
