<p><P>PROBLEM TO BE SOLVED: To provide a polymeric film having satisfactory weather resistance, transparency, flexibility, mechanical strength and toughness. <P>SOLUTION: The melt processed film comprises two polymer components of a first component and a second component. The first component includes a 1C-6C alkylacrylate (co)polymer having Tg of 60-120°C, the second component includes a 1-12C (alkyl)acrylate (co)polymer having Tg lower than 10°C, the gram weight ratio of the two component is less than 0.85. The swelling ratio of the film is at least 15, and one of the polymer components is polymerized in the presence of the other component. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
