Abstract:
Polymeric materials are disclosed herein that include a reaction product of components comprising: a) a first amine component having at least two and at most three primary amino groups, secondary amino groups, or a mixture thereof, with the proviso that the first amine component is not a silicone diamine; b) a second amine component having (i) greater than three primary amino groups, or (ii) at least three primary amino groups and a plurality of secondary amino groups, wherein the second amine component is a polymeric material having a carbon backbone or a polymeric material having a carbon backbone with a plurality of catenated nitrogen atoms; and c) an oxalate ester.
Abstract:
A vapor sensor comprises a housing with an inlet opening in fluid communication with a sensor element within the housing. Standoff member(s) are positioned to maintain a gap between the inlet opening and a skin site. An operating circuit is in electrical communication with the sensor element and communicatively coupled to an output member. In use, the output member generates a sensory output indicative to an operator regarding concentration of alcoholic vapor in the ambient atmosphere proximate the skin site upon receiving communication from the operating circuit.
Abstract:
Film forming gel compositions, useful in creating conformable and flexible gel bandages, can be formulate from a film forming polymer, a tackifier, and a volatile solvent. The film forming gels can also include antiseptics, cationic polymer coagulants, fillers, and other additives. The gel compositions form relatively thick films when dried on tissue, and can exhibit enhanced breathability to promote wound healing.
Abstract:
A siloxane-functional isobutylene copolymer and use thereof is described. The copolymer is of the formula: wherein a is at least 20, and at least one of b and c are at least one, X is oxygen or nitrogen; R1 is a covalent bond or a divalent (hetero)hydrocarbyl group; Sil is a polydialkylsiloxane; and x is 1 or 2.
