Abstract: A method of making a roll of adhesive tape that comprises providing a length of tape having a leading end, a trailing end, a first side, and a second side opposite the first side, wherein the second side of the tape is at least partially covered with pressure sensitive adhesive and providing a tab having first and second opposite ends having a length between them, a first side, and a second side, wherein at least a portion of the second side of the tab is covered with pressure sensitive adhesive. The method further comprises advancing the length of tape along a tape path, positioning the leading tape end about a central tape roll axis, and circumferentially winding the length of tape about the axis until a penultimate tape layer having a circumference is wound.

Abstract: Disclosed is a release material applied to a sheet material that provides for temporary repositioning of an adhesive over the release material. Over time the adhesion between the release material and the applied adhesive builds such that the adhesive cannot be removed from the release material without damaging the underlying sheet material. The release material includes an free nitrogen containing basic group. The release material is dispersed on a flexible substrate and the release material allows for repositioning when contacted with a pressure sensitive adhesive, which includes a free carboxylic acid group, for at least 1 minute and not more than 10 minutes.
Abstract: A tape dispenser including a cutting mechanism is disclosed that allows for improved access to the mandrel during reloading. The tape dispenser comprises a base, a cover, and a mandrel disposed within the base and cover. The cover is capable of securely engaging with the base. The base, the cover, and the mandrel are connected along a pivot point. The cover actuates the mandrel to an open, loading position.

Abstract: A method for the polymerization of free radically polymerizable vinyl monomers involves polymerizing free radically (co)polymerizable vinyl monomers in a batch reaction under essentially adiabatic conditions, and utilizing scavenger monomer to reduce undesirable residual monomer.
Abstract: A flexible barrier assembly having a flexible visible light-transmissive substrate having a Tg greater than or equal to that of heat-stabilized polyethylene terephthalate (“HSPET”) overcoated with a first polymer layer having a Tg greater than or equal to that of HSPET and further overcoated with at least two visible light-transmissive inorganic barrier layers separated by at least one second polymer layer having a Tg greater than or equal to that of HSPET can be used to mount, cover, encapsulate or form moisture- and oxygen-sensitive articles such as organic light emitting devices and light valves.
Abstract: Silicone polyoxamide and silicone polyoxamide-hydrazide copolymers comprise at least two repeating units of formula I In this formula, each R1 is independently an alkyl, haloalkyl, aralkyl, alkenyl, aryl, or aryl substituted with an alkyl, alkoxy, or halo; each Y is independently an alkylene, aralkylene, or a combination thereof; each G is independently a bond or a divalent residue equal to a diamine of formula R3HN-G-NHR3 minus the two —NHR3 groups; each R3 is independently hydrogen or alkyl or R3 taken together with G and with the nitrogen to which they are both attached form a heterocyclic group; each n is independently an integer of 0 to 1500; each p is independently an integer of 1 to 10, and the average of p is 1.2 or greater; and each q is independently an integer of 1 or greater, and every q is not the same integer.
