Abstract:
The present invention is directed to biodegradable microporous materials and multi-layer articles containing them. The biodegradable microporous materials comprise: (a) a polyolefin matrix, (b) finely divided, particulate filler distributed throughout the matrix, (c) at least 35 percent by volume of a network of interconnecting pores communicating throughout the microporous material, and (d) a biodegradation promoting material distributed throughout the matrix. Also provided are multilayer articles prepared from the above-described microporous materials.
