Abstract:
A thermoplastic composition substantially free of elastomers which comprises in admixture:(a) a crystalline polybutene-1 polymer in an amount between about 0.1 and 20% by weight having haze of less than 10% and luminous transmittance of at least 80% as measured by ASTM D1003 95; (b) a crystalline polyolefin polymer of a C2 to C20 olefin monomer other than the polybutene-1 polymer having the haze of less than about 10% and the luminous transmittance of at least about 80% as measured by ASTM D1003 95; (c) an exfoliated layered inorganic nanocomposite derived from a precursor nanocomposite with nanolayers and galleries between the nanolayers in an amount between about 0.1 and 5% by weight, wherein the nanocomposite has been exfoliated by (a), (b) or a mixture of (a) and (b); (d) a coupling agent which couples (a), (b) and (c) together without significantly increasing the haze or reducing the luminous transmittance of the composition in an amount up to about 10% by weight, wherein the composition when molded without pigments has the haze of at least 10% and the luminous transmittance of at least 80%.
