An adhesive tape and methods of use in cold or hot environments, such as in the construction industry, wherein the adhesive tape includes a pressure sensitive adhesive layer (preferably, an acrylic pressure sensitive adhesive layer) disposed on a backing (preferably, a multilayer backing).

Adhesive tapes and methods of use in construction

The tape incudes a water vapor-permeable air and water barrier article and a pressure sensitive adhesive layer. The air and water barrier article includes a fibrous layer having first and second major surfaces and a polymeric layer on a first major surface of the fibrous layer that penetrates into the fibrous layer but leaves at least some fibers exposed on the second major surface. The pressure sensitive adhesive layer is on the polymeric layer of the air and water barrier article. The tape can retain greater than 50 percent by weight of mortar applied according to the Vertical Mortar Receptivity Evaluation. The article includes a substrate, the tape, and a composite layer comprising at least one of gypsum, lime, or cement. The composite layer is at least one of dried or cured on the second major surface of the fibrous layer. Methods of making the article are also described.

Tape, article including tape and composite layer, and related methods

A composition is described comprising semicrystalline polylactic acid polymer; polyvinyl acetate polymer having a glass transition temperature (Tg) of at least 25&#xb0; C.; plasticizer; and optionally amorphous polylactic acid polymer. In another embodiment the composition further comprises nucleating agent. Also described are films comprising the composition as well as articles, such as a tape or sheet, comprising the film described herein and a layer of pressure sensitive adhesive disposed on the film.

Compositions and films comprising polylactic acid polymer, polyvinyl acetate polymer and plasticizer

Described are viscoelastic damping materials and constructions which may demonstrate low temperature performance and adhesion and which may be used in making vibration damping composites. Viscoelastic damping materials and constructions may include polymers or copolymers of monomers according to formula I:CH&#x2550;CHR&#x2014;COOR&#x2003;&#x2003;[I]wherein Ris H, CHor CHCHand Ris a branched alkyl group containing 12 to 32 carbon atoms.

Low temperature vibration damping pressure sensitive adhesives and constructions

Pressure-sensitive adhesive compositions are described comprising polymerized units of (meth)acrylate monomer. Also described are articles comprising such pressure-sensitive adhesive composition.

Adhesives comprising polymerized units of secondary hexyl (meth)acrylates

A film is described comprising a (meth)acrylic polymer and a polyvinyl acetal (e.g. butyral) resin. In some embodiments, the film has a glass transition temperature (i.e. Tg) ranging from 30&#xb0; C. to 60&#xb0; C. In some embodiments, the film has a gel content of at least 20% or greater. In some embodiments, the film has an elongation at break of at least 175%. The film typically comprises photoinitiator as a result of the method by which the film was made. The film may be a monolithic film or a layer of a multilayer film.

Acrylic polyvinyl acetal films and composition

Controlled radical initiators, reaction mixtures containing the controlled radical initiators and various ethylenically unsaturated monomers, polymeric materials formed from the reaction mixtures, crosslinkable compositions containing the polymeric materials, crosslinked compositions formed from the crosslinkable compositions, and articles containing the polymeric materials, the crosslinkable compositions, or the crosslinked compositions are provided. The controlled radical initiators are bis-dithiocarbamate or bis-dithiocarbonate compounds having a single carbon between the two dithiocarbamate or dithiocarbonate groups. Also attached to that single carbon is a ketone group.

Polymeric materials formed using initiators with two thiocarbonylthio-containing groups

Controlled radical initiators, reaction mixtures containing the controlled radical initiators and various ethylenically unsaturated monomers, polymeric materials formed from the reaction mixtures, crosslinkable compositions containing the polymeric materials, crosslinked compositions formed from the crosslinkable compositions, and various articles are provided. The controlled radical initiators are bis-dithiocarbamate or bis-dithiocarbonate compounds having a carbonyl group between the two dithiocarbamate or dithiocarbonate groups.

Polymeric materials formed using initiators with a ketone group and two thiocarbonylthio-containing groups

A film is described comprising a (meth)acrylic polymer and polyvinyl acetal polymer composition, wherein the film comprises a structured layer.

Acrylic films comprising a structured layer

A film is described comprising a first film layer having a Tg ranging from 30&#xb0; C. to 60&#xb0; C. The first film layer comprises a (meth)acrylic polymer and polyvinyl acetal polymer composition. The film further comprises a second layer proximate the first film layer. The second layer is different than the first film layer. The second may be a cured (meth)acrylic polymer film or coating; a backing such as thermoplastic polymer, woven or nonwoven fabrics, metal foils, paper, foams; or a coverfilm such as a fluoropolymer.

Acrylic polyvinyl acetal films comprising a second layer

Controlled radical initiators that are ketone-containing dithiocarbamate or ketone-containing dithiocarbonate compounds are used to form polymeric materials that have a single polymeric block or multiple polymeric blocks. Reaction mixtures containing controlled radical initiators and various ethylenically unsaturated monomers, polymeric materials formed from the reaction mixtures, crosslinkable compositions containing the polymeric materials, crosslinked compositions formed from the crosslinkable compositions, and articles containing the polymeric materials, the crosslinkable compositions, or the crosslinked compositions are provided.

Ketone-containing controlled radical initiators for polymerization reactions

Crosslinkable polymeric materials, crosslinked polymeric materials, articles containing the crosslinkable polymeric materials or crosslinked polymeric materials, and methods of making the articles and various compositions are provided. More particularly, the crosslinkable composition contains a) a first polymeric material, which has terminal dithiocarbamate or dithiocarbonate groups, b) a crosslinking composition containing a chlorinated triazine crosslinking agent and/or a crosslinking monomer having two or more ethylenically unsaturated groups, and c) a thixotropic agent containing metal oxide particles. The crosslinkable composition may be printable or dispensed. In some embodiments, the crosslinked composition is a pressure-sensitive adhesive.
