    Abstract: Disclosed are removable pressure sensitive adhesive compositions (PSAs) useful with facestocks and/or packaging labels designed to be removed in the recycling of polymeric packaging. The PSAs of the invention include (a) at least one monomer which may undergo free radical polymerization and whose homopolymer has a glass transition temperature of less than or equal to 10° C., (b) at least one mono-olefinically unsaturated monomer having aldehyde or ketone functionality, and (c) an effective amount of at least one polyhydrazide crosslinker having hydrazine functionality. The PSA composition of the invention exhibits a peel adhesion value of between about 0.4 lbs/in (70 N/m) and about 4 lbs/in (700 N/m), and the percent film remaining on the polymeric packaging after a sink-float testing is 0% to about 8%.

    Abstract: Embodiments of the present disclosure generally relate to phenolic resin compositions, methods for preparing the same, and uses thereof. In an embodiment, a resin composition is provided. The resin composition includes a wax emulsion and a polymer composition that includes an alkylphenol-phenol-aldehyde polymer, the alkylphenol-phenol-aldehyde polymer including: alkylphenol monomer units; and phenol compound co-monomer units. In another embodiment is provided an article of manufacture that includes a lignocellulosic substrate, and a resin composition that includes an alkylphenol-phenol-aldehyde polymer, a polyhydric alcohol, and a wax emulsion.

    Abstract: Compositions, methods, and resins using alkyl aldehydes and phenols are provided herein. In one embodiment, a composition comprising an alkylphenol resin can be prepared by condensing at least one phenolic monomer selected from the group consisting of phenol, cresol, resorcinol, xylenol, ethyl phenol, alkylresorcinols, and combinations thereof; and at least one alkyl aldehyde having from 5 to 12 carbon atom alkyl groups. The alkylphenol resins of the application are free of octylphenol or nonylphenol monomers. In one embodiment, the alkylphenol resins may be prepared using formaldehyde, and alternatively, in another embodiment, the alkylphenol resins may be prepared without the use of formaldehyde. The process to make these new alternative alkylphenol resins is a cost effective process and easy to scale-up.

    Abstract: A method of making a proppant-gel matrix comprising: a) hydrating a gelling agent to form a hydrated gelling agent; b) adding a basic compound to the hydrated gelling agent to form a basic hydrated gelling agent having a pH in the range of 11.5 to 14.0; c) mixing the basic hydrated gelling agent and a proppant to form a basic hydrated gelling system; and d) adding a crosslinking agent to the basic hydrated gelling system to form the proppant-gel matrix, is disclosed. The proppant-gel matrix can then be used as a fracturing fluid in a hydraulic fracturing process.
