preparation example Construction

[0107] Some suitable methods for preparing block copolymers are living polymerization methods. The term "living polymerization" as used herein refers to a polymerization technique, process or reaction in which the amplified species do not undergo termination or transfer. Further polymerization can occur if additional monomer is added after 100% conversion.

[0108] Because the number of amplified species does not change, the molecular weight of the living polymer increases linearly as the conversion progresses. Living polymerization methods include, for example, living radical polymerization techniques and living anionic polymerization techniques. Specific examples of living radical polymerization include atom transfer polymerization and reversible addition-fragmentation chain transfer polymerization.

[0109] Block copolymers prepared using living polymerization methods tend to have well-controlled blocks. The term "well-controlled" as used herein in relation to methods of...

Embodiment 2

[0173] Embodiment 2 is the method of embodiment 1, wherein the sealant composition further comprises at least one polymer dissolved in the solvent.

Embodiment 3

[0174] Embodiment 3 is the method of embodiment 2, wherein the at least one polymer comprises a fluoropolymer, a non-tacky (meth)acrylate-based block copolymer at ambient temperature, or a combination thereof.

Abstract

Methods for preparing edge-sealed multi-layer film articles include applying a sealant composition to a multi-layer film article that includes at least one polymeric film layer, and permitting the sealant composition to dry to form an edge-sealed article. The sealant composition includes at least one solvent capable of softening, penetrating or dissolving the polymeric film layer of the multi-layer film article, and at least one polymer dissolved in the solvent. The polymer dissolved in the solvent may be a fluoropolymer, a non-tacky at ambient temperatures (meth)acrylate-based block copolymer, or a combination thereof. Edge-sealed articles prepared by this method can include other polymeric film layers or coated layers such as metallic layers and can be part of larger assemblies.

Description

technical field [0001] The present disclosure relates to methods for sealing edges of multilayer articles and edge-sealed multilayer articles. Background technique [0002] A wide variety of multilayer articles are prepared and used in a variety of applications. Some of these articles are exposed to environments that may be problematic for these articles. For example, some articles are exposed to the external environment and thus to water (rain, fog, mist, dew, etc.), temperature changes (both hot and cold), wind, and pollutants such as dust, salt, oil, etc. These exposures can cause problems such as delamination of layers where one or more layers become or begin to become separated from adjacent layers. Once the process begins, it can rapidly expand and cause significant damage to the article. [0003] To inhibit delamination, various articles and techniques have been used to seal the edges of the article, including the use of heat seals and the use of tapes that cover t...
