  • Gel composition comprising a phase change material
    Patent number: 11655408
    Abstract: The present invention provides a composition comprising a) a phase change material; b) 1 to 10 wt % of a silica gelling additive; and c) a styrene co-polymer gelling additive; wherein the composition is in the form of a gel and wherein the weight ratio of b) silica gelling additive to c) styrene co-polymer gelling additive in the composition is in the range from 0.6 to 5:1. The invention also provides a method of making the composition and an article and a product comprising the composition. Finally, the invention provides the use of a combination of a silica gelling additive and a styrene co-polymer gelling additive to make a gel composition comprising a phase change material with one or more improved properties.

  • Process for producing high-performance polymer fibers
    Patent number: 9205589
    Abstract: The present invention relates to a process for the preparation of polymer filaments having a high tensile strength and modulus by extrusion of a solution of a solvent and linear high-molecular weight polymer and subsequent spinning and quenching of the filaments thus formed, wherein after spinning and quenching the as-spun filaments are stretched under contact with steam for removing the solvent from filaments being stretched.
