The present application discloses interlayers comprising novel polyesteramides comprising diols with tunable properties based on the monomers and monomer ratios used to prepare the polyesteramides and varying the reaction conditions. The interlayers have improved properties and can be used in many different applications.

A poly(ester amide) polymer having free carboxylic acid pendant groups and method of making and using the same are disclosed.

A poly(ester amide) polymer having free carboxylic acid pendant groups and method of making and using the same are disclosed.

A braided structure that includes a core and a sheath is provided. The core includes a yarn formed at least in part from an aromatic polymer (e.g., an aromatic polyester/liquid crystalline polymer or an aramid polymer), and the sheath, which includes a plurality of ultra high molecular weight polyolefin yarns, is braided around the core. The sheath has an overall diameter ranging from about 60 micrometers to about 650 micrometers. Despite its small diameter, the braided structure can be creep resistant and abrasion resistant while at the same time exhibiting low elongation, a high load at break, and high stiffness. The braided structure can be used in medical applications such as sutures, load bearing orthopedic applications, artificial tendons/ligaments, fixation devices, actuation cables, components for tissue repair, etc.
