Improved thermoplastic polymer blend compositions comprising an isotactic polypropylene component and an alpha-olefin and propylene copolymer component, said copolymer comprising crystallizable alpha-olefin sequences. A change log is used with a client database for synchronizing the database. The balanced integrated circuit coupling couples the plurality of power amplifiers to the up-conversion module such that the power amplifiers amplify the up-converted signal to produce a plurality of amplified radio frequency signals. Methods of preparing the dry film coatings, methods of preparing corresponding aqueous suspensions, methods of applying the coatings to substrates and the coated substrates themselves are also disclosed.
