The present invention is an oil-resistant adhesive composition including a hydroxy alkyl (meth)acrylate having an alkyl group containing 2 to 4 carbons, a short alkyl (meth)acrylate having an alkyl group containing 6 or less carbons, and a photo-initiator. After the adhesive composition is soaked in oleic acid at room temperature for 7 days, the adhesive composition has an expansion percent of less than about 10%.

Oil-resistant optically clear adhesives

The present disclosure provides a photopolymerizable composition. The photopolymerizable composition includes at least one urethane component, at least one monofunctional reactive diluent, an initiator, and optionally an inhibitor. The present disclosure also provides an article including the reaction product of the photopolymerizable composition. Further, the present disclosure provides a method of making an article. The method includes (i) providing a photopolymerizable composition and (ii) selectively curing the photopolymerizable composition to form an article. The method optionally also includes (iii) curing unpolymerized urethane component and/or reactive diluent remaining after step (ii). Further, methods are provided, including receiving, by a manufacturing device having one or more processors, a digital object comprising data specifying an article; and generating, with the manufacturing device by an additive manufacturing process, the article based on the digital object. A system is also provided, including a display that displays a 3D model of an article; and one or more processors that, in response to the 3D model selected by a user, cause a 3D printer to create a physical object of an article.

The present disclosure provides a polymeric material including a polymerized reaction product of a polymerizable composition including components and has a solids content of 90% or greater. The components include a uretdione-containing material including a reaction product of a diisocyanate reacted with itself; a first hydroxyl-containing compound; an optional second hydroxyl-containing compound having a single OH group, wherein; and an epoxy component. The first hydroxyl-containing compound has more than one OH group and the optional second hydroxyl-containing compound is a primary alcohol or a secondary alcohol. The present disclosure also provides a two-part composition, in which the polymeric material is included in the first part and the second part includes at least one amine. Further, a method of adhering two substrates is provided, including obtaining a two-part composition; combining at least a portion of the first part with at least a portion of the second part to form a mixture; disposing at least a portion of the mixture on a first substrate; and contacting a second substrate with the mixture disposed on the first substrate. The disclosure also provides a polymeric material and a method of making a two-part composition. Advantageously, two-part compositions according to the present disclosure can be used as coatings and adhesive systems with handling and performance similar to existing two-part urethane systems, but with less sensitivity to water.

Articles that contain a solid support with a grafted chain extending from the solid support, methods of making these articles, and various uses of the articles are described. More specifically, the grafted chain has a functional group that can react with or interact with target compound. Alternatively, the functional group on the grafted chain can react with a modifying agent to provide another group that can react with or interact with the target compound. The grafted chains are attached to the solid support through a ring-opened azlactone group. The articles can be used to purify the target compound or to separate the target compound from other molecules in a sample.
