Provided is a polymer from which an encapsulant excellent in weather resistance and processability can be obtained when being used for an encapsulant for a solar cell. The polymer that has a main chain comprising repeating units represented by formula (1) and repeating units represented by formula (2) and satisfies requirements (a1), (a2), and (a3), ##STR00001##
(a1): the ratio of the number of the repeating units represented by formula (2) to the total number of the carbon atoms that constitute the main chain of the polymer is from 3.8% to 7.5%;
(a2): the ratio X represented by formula (3) is from 82% to 100%;
X=100A/B(3)
(a3): the polymer has a melting point of 42 C. to 90 C. as measured with a differential scanning calorimeter.

Multi-layer packaging articles can include embossments formed on each layer. A bonding element fixes the embossments on one layer to corresponding embossments on another layer. The bonding element can be a heat-activatable material, including a thermoplastic material. The bonding element can have a stability that permits the bonding element to retain its ability to form a satisfactory bond after being exposed to the ambient environment in an un-activated state.

The disclosure relates to compositions and methods useful for treating a substrate, for example for preventing or inhibiting corrosion of metal substrates. The compositions comprise (a) at least one cross-linkable, partially hydrolyzed polymer, and (b) at least one particular crosslinking agent.

A material restoration system for restoring material surfaces, the material restoration system comprising: a first composition including at least fifty percent alcohol by volume; at least twenty percent cutting oil by volume; denatured alcohol; C9-11 Pareth-8; Sodium C14-16; Sodium laureth sulfate; Sodium chloride; and Sodium xylenesulfonate.

A coated paper liner serves as both exterior packaging and an interior release liner for consumer products. The liner comprises a paper sheet layer with a first polymeric composition, such as a thermoplastic elastomer or polymer, forming a film on at least a portion of a surface of the paper sheet. The liner may comprise a flexibility agent that enhances pliability and noise reduction during handling. The liner may also include a release agent, such as silicone, to prevent adhesion of consumer products to the liner. The method of manufacturing involves coating the paper sheet with the polymeric composition and flexibility agent, followed by drying. This solution offers a sustainable alternative to plastic films, providing to the liner heat-sealability, barrier properties, and recyclability.
