ABSTRACT:
The properties of (meth)acrylic ester/(meth)acrylic acid copolymer webs, such as films and nonwovens, are improved by blending the ester/acid copolymer with a modified polyolefin, such as an ethylene/(meth)acrylic acid copolymer and/or a styrene/butadiene block copolymer, and a polyether block amide copolymer. The copolymer blend provides a polymeric material which is useful for making personal care products such as diapers and feminine pads in that it can be made water-soluble in alkaline solutions while exhibiting other properties which are necessary for adequate product performance. Such materials are also useful for packaging products, such as film for plastic bags and the like.
