Disclosed herein is an isosorbide-based polycarbonate polymer comprising: an isosorbide unit, an aliphatic unit derived from a C14-44 aliphatic diacid, C14-44 aliphatic diol, or combination of these; and optionally, an additional unit different from the isosorbide and aliphatic units, wherein the isosorbide unit, aliphatic unit, and additional unit are each carbonate, or a combination of carbonate and ester units. Also disclosed are a thermoplastic composition and an article comprising the isosorbide-based polycarbonate.

Isosorbide-based polycarbonates, method of making, and articles formed therefrom

A method of making a microstructure includes selectively activating a portion of a surface of a silicon-containing elastomer, contacting the activated portion with a substance, and bonding the activated portion and the substance, such that the activated portion of the surface and the substance in contact with the activated portion are irreversibly attached. The selective activation may be accomplished by positioning a mask on the surface of the silicon-containing elastomer, and irradiating the exposed portion with UV radiation.
