One method for making a laminate material comprising a first surface layer
comprising resorcinol arylate polyester chain members and a second
surface layer suitable for bonding to a substrate, comprises co-extruding
a polymeric first surface layer material and a polymeric second surface
layer material through a die and into the first nip of a calender roll
stack comprising a first surface roll and a second surface roll that
define the first nip, to form the laminate material. A nip load in the
first nip of greater than or equal to about 400 N/cm can be applied to
the laminate, and the laminate material can be collected from the roll
stack. The first roll and the second roll can each have a surface
smoothness of less than or equal to about 5 micrometers and temperatures
of about 40.degree. C. to about 150.degree. C.
