Abstract
Official abstract text for this publication.
The present disclosure provides a method of providing an adhesive composition comprising the steps of combining crosslinkable composition including: a) a (meth)acryloyl monomer mixture with the b) photocrosslinking agent mixture, and irradiating with UVC radiation to polymerize and crosslink the composition.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of preparing a (meth)acrylate adhesive composition comprising: a) providing a (meth)acryloyl monomer mixture and a photoinitiator, b) irradiating the mixture with UVA to partially polymerize the monomer mixture to a syrup copolymer; c) adding additional photoinitiator and optionally a multifunctional (meth)acrylate, followed by; d) combining the syrup polymer of steps b) or c) with a photocrosslinking mixture comprising: i) a benzopheno…
