摘要：从交联聚烯烃制备闭孔泡沫体的方法，包括把含有发泡剂和交联剂的可发泡和可交联的聚烯烃混合物注入一个密封的模内，然后在压力下形成有相应形状的可发泡产物，在交联作用进行期间，发泡剂并未分解。然后把可发泡的交联产物置于一对金属板之间加热，使该产物在金属板之间的空间内双轴膨胀。接着把所得的产物在大气压力下加热，使该中间产物向各方膨胀，从而形成完全发泡的成型体，同时剩余的发泡剂亦完全分解。

摘要： Foams are prepared from a linear low density polyethylene having a Vicat softening temperature, as measured by ASTM test method designated D-1525-75 of less than 105oC, and optionally, other olefinic polymers, such as a low density polyethylene using a chemical cross-linking agent. The resulting cross-linked polyethylene foams exhibit an excellent ballance of properties at generally lower densities than foams prepared from low density polyethylene only.

摘要： An absorbent, microporous foam comprising a crosslinked polymer having interconnected fluid cells distributed throughout its mass, wherein the fluid cells have a diameter of between about 0.1 and about 100 mu m, and wherein the foam can rapidly absorb at least about twice its dry weight in fluid, is disclosed. A method for producing a microporous, absorbent foam is also disclosed. This method comprises the steps of: (a) mixing a cross-linkable polymer and a first solvent to form a stable solution, wherein the stable solution can be induced to phase separate; (b) inducing the stable solution to phase separate into a polymer-concentrated phase and a polymer-dilute phase after a predetermined period of time; (c) inducing crosslinking of said polymer, so that the polymer will crosslink in said concentrated phase for a predetermined period of time during phase separation to thereby form a microporous material; and (d) drying the microporous material to produce the absorbent foam.

摘要： A process for continuously manufacturing, under ordinary pressure, heat-resistant crosslinked vinyl chloride resin foam having a low density and uniform, fine cells, which process comprises a first step of gelling a mixture of vinyl chloride resin, plasticizer, stabilizer, crosslinking aid, and blowing agent under such conditions that the blowing agent is not decomposed, and then molding the thus gelled mixture into a desired shape; a second step of crosslinking the resulting molding by irradiation with an ionizing radiation; and a third step of heating the thus crosslinked product to expand it.
