are best when the content
of

is
10%. The initial tensile strength is 19.27 MPu, after the
accelerating

fest if
remained
above 86%. The thermal gravimetric analysis (TCA) showed that the polymer blend with
f()°/"SAN was resistant up to 25(J'C. This polymer would be degraded more slowly than that
of
the
polymer blend without SAN.
