Abstract: The present invention is a transparent thermoplastic polyurethane (TPU) comprising structural units of: a.) a diisocyanate; b.1) a polyester diol and b.2) a specific polyether diol and c.) a chain extender. The TPU has good combinations of light transmission and clarity, tensile strength, low temperature flexibility, and high moisture vapor transition rates compared to other commercial or known TPUs. A preferred example composition is a TPU that is based on MDI as the diisocyanate monomer, polycaprolactone as a polyester diol, an EO capped EO/PO polyether diol containing less than 20% EO, and butanediol as chain extender. These composition have good combinations of clarity, tensile strength, hydrolytic stability and processability compared to TPUs prepared using either polyester or polyether diols alone or the combination with a higher EO polyether diol.

Abstract: The present invention is a low haze thermoplastic polyurethane (TPU) prepared from a chain extender mixture that includes an acyclic diol and a mixture of 1,3- and 1,4-cyclohexanedimethanol. The TPU elastomers exhibit good optical clarity, particularly when formed into relatively thick injection molded parts.

Abstract: A the process of producing a hydrophobically modified polymer that can be used as a cosmetically acceptable composition prepared by incorporating hydrophobic moieties into a polymer composed acrylamide, one or more cationic monomers and optionally one or more anionic monomers. The composition may be incorporated into products for treating hair, skin and nails and also into household products such as household cleaners and laundry detergents.

Abstract: A method of treating one or more hair shafts, each hair shaft including a cuticle layer and a cortex enclosed in the cuticle layer is disclosed. The method comprises: selecting one or more polymers that can penetrate the hair shafts with a pore size of about 5 angstroms to about 5000 angstroms; and treating the hair shafts by applying an effective amount of a composition containing said polymers to said hair shafts.

Abstract: A sprinkler system comprises a network of CPVC conduits and a plurality of sprinklers. The system includes an electrically activated solenoid control valve to allow fluid to flow in the pipe network. One or more fire detectors operate independently of the condition of the sprinklers. Upon detection of an incipient fire situation, a fire detector sends an electrical signal to cause activation of the control valve. Upon activation of the control valve, fire suppression fluid is caused to flow through the conduits before the incipient fire situation matures into a sprinkler-triggering event. The cooling effect of fluid flowing through the conduit enables the conduit to resist structural failure prior to sprinkler deployment. The control valve may be disposed at a remote location in the sprinkler line and be operable as part of an inspector's test connection.
Abstract: The invention relates to lubricants which contain a phosphorus to nitrogen ratio of ?1.0 and a sulfur content of >1.4 wt. %. The phosphorus contribution is primarily from an acid phosphate species and the sulfur content is primarily from an antiwear agent. This lubricant composition has been found to provide exceptional protection to new gears or “green gears”, during the break-in phase.
