A composite polymeric material is provided that may be used to construct
an abrasion resistant layer or sheet such as an abrasion resistant
meltblown layer. Desirably, the composite polymeric material comprises
blends of syndiotactic and isotactic polypropylene with ferroelectric
materials. The composite polymeric material is particularly useful for
constructing a filter media comprising an abrasion resistant fine fiber
layer such as a nonwoven layer. The composite polymeric material of the
present invention also allows for electret treatment to improve its
filtration characteristics.
