Abstract: A thermoplastic composition comprises: a copolycarbonate comprising bisphenol A carbonate units and second carbonate units of the formula (I) and optionally, a bisphenol A homopolycarbonate; wherein the second carbonate units are present in an amount of 10 to 49 mol % based on the sum of the moles of the copolycarbonate and the bisphenol A homopolycarbonate, the copolycarbonate comprises less than 2 ppm by weight of each of an ion of lithium, sodium, potassium, calcium, magnesium, ammonium, chlorine, bromine, fluorine, nitrite, nitrate, phosphite, phosphate, sulfate, formate, acetate, citrate, oxalate, trimethylammonium, and triethylammonium, as measured by ion chromatography, and the thermoplastic composition has a bisphenol A purity of at least 99.6%, or at least 99.7% as determined by high performance liquid chromatography. The thermoplastic composition has a Vicat B120 of 155° C. or higher; and an increase in yellowness index of less than 10 during 1000 hours of heat aging at 155° C.

Abstract: A microneedle includes a shaft having a proximal end and a distal end and a capillary space within the shaft, the capillary space (i) connecting the proximal and distal ends or (ii) extending from the distal end of the shaft and connecting with one or more external openings positioned between the proximal end and distal end or (iii) performing the functions of both (i) and (ii). The microneedle includes a polymer mixture which includes (a) optionally polycarbonate, (b) a polycarbonate-polysiloxane copolymer and (c) a mold release agent.

Abstract: A lens containing a polycarbonate composition is disclosed. The polycarbonate composition includes a copolycarbonate having bisphenol A carbonate units and second carbonate units of the formula and 2 to 40 ppm of an organosulfonic stabilizer of the formula wherein the second carbonate units are present in an amount of 20 to 49 mol %, preferably 30 to 40 mol % based on the sum of the moles of the copolycarbonate and the bisphenol A homopolycarbonate. The polycarbonate composition has: a Vicat B120 of 160° C. or higher measured according to ISO 306; and a yellowness index of less than 12, measured according to ASTM D1925.
