The present invention relates to a polymer comprising a repeating group having the structure of formula (I)

##STR00001##

wherein R, R.sup.1, R.sup.2, R.sup.3, R.sup.4, X, and s are as described herein and salt thereof. Also disclosed is a process of synthesizing such polymers.

Shape memory polymers featuring reversible actuation capability under ambient stimulus for integration with apparel. One approach is to use a multiblock polymer consisting of two (or potentially more) blocks in which the one block is the crystalline switching block with relatively low melting transitions, the other block has a higher thermal transition, and the two blocks are linked together by a linker molecule. Another approach is to use a graft copolymer having high and low melting transitions where the graft copolymer has a first polymer serving as the backbone and a second polymer being grafted to or from the backbone at certain graft locations. A further approach is to use latent crosslinking of a semicrystalline polymer with reactive groups placed on the backbone.
