A contact lens and a manufacturing method thereof are proposed. The contact lens may include a resin composition containing an acrylic-based monomer and a Boswellia extract. By containing a Boswellia extract, the contact lens can prevent adherence of bacteria when worn on the user's eye and serve as an antibacterial agent to prevent bacterial infection, so it can secure a good contact fit and high antibacterial performance.

Some variations provide a sensing system configured to measure the concentration of an antimicrobial agent in a polymer, comprising: a polymer containing (i) a discrete solid structural phase comprising a solid structural polymer and (ii) a continuous transport phase comprising a solid transport polymer and capable of containing the antimicrobial agent; and an antimicrobial-agent sensor that chemically senses the antimicrobial agent. The antimicrobial-agent sensor is disposed on a surface of, and in mass transport with, the polymer. The antimicrobial-agent sensor contains a responsive material disposed on or within a carrier material. The responsive material is chemically reactive with the antimicrobial agent and exhibits an observable and quantifiable property change upon chemically reacting with the antimicrobial agent. The observable and quantifiable property change may involve chromaticity, optical transparency, ionic conductivity, or electronic conductivity, for example. Some variations provide methods of making and/or using the sensing system.

Two-part condensation curable silyl-modified polymer (SMP) based sealant compositions, in particular two-part condensation curable SMP based translucent sealant compositions containing a catalyst comprising (i) a titanate and/or zirconate and (ii) a metal carboxylate salt.

Provided herein is a formulation containing a PPG/PEG block-copolymer (I) on average having PEG-blocks in the range of 37-45 terminated on both sides with on average in the range of 6-11 PPG blocks. The PPG/PEG block-copolymer can be end capped with hydrocarbon systems like for example n-butyl. The PPG/PEG block-copolymer (I) is chosen to have a DSC-melting point according to DIN ISO 11357 in the range of 15-37° C. to provide for a cool touch effect and can be applied without encapsulation. Furthermore uses of such a formulation and textiles treated with such a formulation are proposed.
