Microporous material having degradation properties and articles prepared therefrom

摘要

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.

1. A biodegradable microporous material comprising:
(a) a polyolefin matrix, (b) finely divided, substantially water-insoluble particulate filler distributed throughout the polyolefin matrix, said filler constituting from 30 to 90 weight percent of the microporous material, (c) at least 35 percent by volume of a network of interconnecting pores communicating throughout the microporous material, and (d) an amount of biodegradation promoting material distributed throughout the polyolefin matrix that is sufficient to render the microporous material biodegradable, said biodegradation promoting material comprising a furanone compound, a glutatic acid, a hexadecanoic acid compound, an organoleptic swelling agent or mixtures thereof.
