Abstract
Compositions of ethylene alkyl acrylate grafted onto a polyolefin such as isotactic polypropylene are provided. The composition is highly wettable by adding both a polar group material and a hydrophilic modifier to the polypropylene. The hydrophilic modifier comprises a monoglyceride and a salt of a linear alkyl. The process comprises extruding the polyolefin into a fiber which is spinnable and may be used to form woven or nonwoven materials. The composition products are particularly well suited for forming various goods, including diaper coverstock, personal hygiene pads, battery separators, filters, tea bag pouches and filter stock.
