    摘要： New linear polyurethane elastomers have been developed by combining a polycarbonate polyol, a polyether polyol, at least two extenders, and a solid diisocyanate compound. Preferably, the diisocyanate compound is modified by reaction with one of the extenders to form a modified diisocyanate component which is a liquid at room temperature prior to reaction with the polyols and other extender. These new elastomers possess a unique combination of hydrolytic stability, toughness, flexibility, and relatively low temperature processability.

    摘要： Linear polyurethane elastomers of a polyol component, at least two extender components, and a diisocyanate compound are prepared by reacting the diisocyanate compound with one of the extender components to form a modified diisocyanate component having a functionality of about 2 prior to reacting this modified component with the other components of the elastomer. These new elastomers can be processed at lower temperatures compared to elastomers prepared from similar compositions wherein the isocyanate compound is not modified.

    摘要： An oxygen scavenging composition of a carrier, such as a polymer, which is permeable to both oxygen and water or water vapor and an oxygen scavenging compound of an organic compound or salt thereof dispersed relatively uniformly throughout the polymer in an amount effective to act as an oxygen scavenger. The oxygen scavenging compound is a salicylic acid chelate or complex of a transition metal or a salt thereof. The oxygen scavenging composition is activated for scavenging oxygen by contact with water or water vapor which permeates into or through the carrier. A reducing agent of an ascorbate compound may be added to enhance the performance of the salicylic acid chelate or complex. The oxygen scavenging compound may be added to the composition in a dry state, and is inactive until activated for oxygen scavenging by contact with water or water vapor.

    摘要： An oxygen scavenging composition of a polymer which is permeable to both oxygen and water or water vapor, and an oxygen scavenging material of an amino polycarboxylic acid chelate or complex of a transition metal, or salt thereof, dispersed relatively uniformly throughout the polymer in an amount effective to act as an oxygen scavenger when activated for scavenging oxygen by contact with water or water vapor which permeates the polymer. A preferred oxygen scavenging compound is ferrous EDTA or salts thereof. Also, an ascorbate compound may be used as a preservative or augmenter for the oxygen scavenging compound.

    摘要： An oxygen scavenging composition of a carrier, such as a polymer, which is permeable to both oxygen and water or water vapor and an oxygen scavenging compound of an organic compound or salt thereof dispersed relatively uniformly throughout the polymer in an amount effective to act as an oxygen scavenger. The oxygen scavenging compound is activated for scavenging oxygen by contact with water or water vapor which permeates into or through the carrier. Also, a catalyzing agent is included in an amount sufficient to increase the rate of oxygen scavenging by the organic compound. The organic compound and catalyzing agent are preferably maintained in a dry state by freeze drying or microencapsulation until the organic compound is activated for oxygen scavenging by contact with water or water vapor.
