<p><P>PROBLEM TO BE SOLVED: To provide an intermediate film for laminated glass for making it unnecessary to perform any moisture conditioning process, and for obtaining sufficient adhesivity and traceability with a glass plate although lamination with the glass plate is simple, and for holding toughness in a wide temperature range, and for making it hard to generate discoloration against direct sunshine or ultraviolet rays, and for obtaining excellent weather resistance and transparency. <P>SOLUTION: The intermediate film for laminated glass includes an ionomer resin configured such that a binary copolymer composed of (A) ethylene and (B) (meth)acrylic acid or (meth)acrylic acid acrylic ester is crosslinked with a metal ion, and that MFR in 190°C×2.16 Kgf is 5 to 15 g/10 min. In this case, it is desired that an ultraviolet absorber and light stabilizer and antioxidant are also contained, and that the molecular weight of the ultraviolet absorber is 450 g/mol or more. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
