    • A degradable polymer network is obtained by adding from 0.2 to 10 parts by weight of a foaming agent to 100 parts by weight of a polylactic acid-base resin composition comprising from 80 to 100 % by weight of polyactic acid or a lactic acid-hydroxycarboxylic acid copolymer and from 0 to 20 % by weight of a plasticizer, conducting melt-foaming extrusion of resulting mixture, and opening the foam cells in the extrudate by stretching. The high polymer network is characterized in suitable flexibility and hydrolyzability and thus useful as a material for absorbers of oils and body fluids, screens for sunlight, heat-isulating materials, filter media and packaging materials; and does not accumulate as industrial wast because of hydrolyzability in the natural environment, even though discarded after use.
    • 通过将0.2〜10重量份的发泡剂加入到100重量份的聚乳酸类树脂组合物中,得到可降解聚合物网络,所述聚乳酸类树脂组合物含有80〜100重量%的聚乳酸或乳酸 - 羟基羧酸 共聚物和0至20重量%的增塑剂,对所得混合物进行熔融发泡挤出,并通过拉伸打开挤出物中的泡沫细胞。 高聚物网络的特征在于具有合适的柔性和水解性,因此可用作油和体液吸收剂的材料,用于阳光的屏幕,热包覆材料,过滤介质和包装材料; 并且由于天然环境中的水解性而不会作为工业废物积聚,即使在使用后被丢弃。
