Dynamics of Polyether Polyols and Polyether Carbonate Polyols

Macromolecules, 2016
The presence of carbonate groups along the polymer backbone of polyether carbonate polyols leads to distinctly different physicochemical properties compared to structurally related polyether polyols. For instance, polyether carbonate polyols are characterized by their substantially higher viscosity. Targeting at understanding the underlying reasons for

A Polyether Impression Rubber

Journal of Dental Research, 1972
An imine-terminated polyether impression rubber was studied. Setting is effected by an aromatic sulfonate ester. The material is clean handling, odorless, and quick setting. Dimensional stability in air is good, but exposure to water may cause difficulty.

The Boston All-in-One Medial Patellofemoral Complex Reconstruction: A Combined Medial Patellofemoral Ligament and Medial Quadriceps Tendon Femoral Ligament Dynamic Tensioning Technique Using Allograft. [PDF]

Arthrosc Tech
Abstract Recent anatomical understanding of the medial restraints of the patella has evolved over the last decade with a current focus on the medial quadriceps tendon femoral ligament, a distinct anatomical structure to the medial patellofemoral ligament. These combine to form the medial patellofemoral complex. This technical note describes a technique
