TL;DR: Most of the formulations released ibuprofen by an anomalous (non-Fickian) transport mechanism, except those matrices that contained methylcellulose and Gelcarin (in a 1:1 and 1:2 ratio), which showed zero-order release.

TL;DR: Dynamic polymers based on acylhydrazone bonds in the linear main chains were found to show bond exchange leading to crossover component recombination as neat polymers even at room temperature under acid catalysis, thus generating randomized copolymers.

TL;DR: In this article, the authors presented novel golf ball compositions which contain non-ionic olefinic copolymers produced by use of metallocene catalysts, wherein the metallocenes catalyzed polymers have been functionalized with a post-polymerization reaction.
Abstract: The disclosed invention provides novel golf ball compositions which contain non-ionic olefinic copolymers produced by use of metallocene catalysts, wherein the metallocene catalyzed polymers have been functionalized with a post-polymerization reaction. The grafted metallocene catalyzed polymers may be blended with ionomers, non-grafted metallocene catalyzed polymers, or other non-ionomeric polymers. These compositions exhibit improved mechanical properties such as tensile and flexural properties, and can be foamed or unfoamed. Golf balls that employ at least one layer of these compositions in any of the golf ball cover, core, or a mantle situated between the cover and the core provide ball properties and performance similar to and in some cases better than the state of the art ionomer based golf balls.

TL;DR: The thermodynamics of mixing of two miscible or immiscible polymers with a solid has been considered in this paper, and it is shown theoretically that the introduction of a specific filler in binary polymer mixtures increases the thermodynamic stability of the ternary system.

TL;DR: A series of 10 binary blends of poly(9,9-dioctylfluorene) and regioregular poly(3-hexylthiophene) were investigated and found to be phase separated and to exhibit high field-effect mobility of holes.
Abstract: A series of 10 binary blends of poly(9,9-dioctylfluorene) and regioregular poly(3-hexylthiophene) were investigated and found to be phase separated and to exhibit high field-effect mobility of holes. The mobility of holes determined from blend thin film transistors was in the range of 2.0 × 10-4−1 × 10-3 cm2/(V s) in blends of 10−80 wt % poly(9,9-dioctylfluorene). A concave-upward dependence of hole mobility on blend composition was found with a minimum in mobility around the symmetric blend composition (50 wt %). The field-effect mobility of holes in poly(9,9-dioctylfluorene) homopolymer could not be determined directly because of the barrier to charge injection from gold electrodes. However, from the composition-dependent field-effect mobility of holes in the series of binary blends, we estimated the hole mobility in poly(9,9-dioctylfluorene) homopolymer to be (6−10) × 10-4 cm2/(V s), which is in good agreement with previous results obtained by the time-of-flight technique. These results demonstrate tha...
