Patent ID: 7498385

Claim:
A composite article comprising: a. first material comprising fluoropolymer, and b. second material comprising a crosslinked semicrystalline polyester shape memory polymer, wherein the crosslinked semicrystalline polyester shape memory polymer has a backbone consisting essentially of linked ester units A, B, and C of the formulae: where R 1 has the formula: —[CH 2 ] a — where R 2 has the formula: R 3 has the formula: R 4 has the formula: —[CH 2 ] f — where a and f are, independently integers between 2 and 35, and b, c, d and e are, independently, integers between 1 and 35, and wherein β and φ are given by the formulae: β = [ moles ⁢ ⁢ R 1 + moles ⁢ ⁢ R 2 + moles ⁢ ⁢ R 3 ] moles ⁢ ⁢ R 4 φ = [ moles ⁢ ⁢ R 2 + moles ⁢ ⁢ R 3 ] [ moles ⁢ ⁢ R 1 + moles ⁢ ⁢ R 2 + moles ⁢ ⁢ R 3 ] and satisfy the following expressions: 0.9≦β≦1.2, 0.20≦φ≦0.80.
