Abstract: A method for separating a polymer-containing composition from a substrate coated with the composition is described, the method comprising contacting the coated substrate with an acidic solution under conditions sufficient to separate the composition from the substrate which can then be recycled, wherein at least one polymer present in the polymer-containing composition is formed from at least one monomer having one or more functional groups which form acid-labile (reversible) covalent crosslinking bonds with the substrate and/or with a different polymer present in the polymer-containing composition and/or with itself.

Abstract: Hydrocarbon swelling particles for wellbore cementing include a crosslinked polymer comprising vinyl aromatic monomer and/or (meth)acrylic monomer.

Abstract: An aqueous composition that can be used to provide a release release properties to adhesive tape substrates can be applied at coating weights far less than those required in previously available compositions containing the same or similar release polymers. Inclusion of small amounts of a superwetter results in improved coatability and reduced amounts of sound generated during the process of releasing an adhesive tape from its roll.
