  • POLYMER ADDITIVES FOR PRESSURE-SENSITIVE ADHESIVES
    Publication number: 20200392381
    Abstract: Core-shell copolymers are described, along with methods of making same, which provide improved adhesion and cohesion when used as additives in pressure sensitive adhesives. The core-shell polymers contain copolymers with ureido functionality in the shell region only, while the core region is substantially free of ureido functionality.

  • Radiation curable compositions containing cyanoalkoxyalkyl and cyanothiaalkylalkyl acrylates
    Patent number: 4360540
    Abstract: There are disclosed radiation curable compositions containing (a) about 5-95% by weight of at least one cyanoalkoxyalkyl or cyanothiaalkylalkyl acrylate, (b) about 1-90% by weight of a photopolymerizable acrylated polymer or oil, and (c) from 0 to about 5% by weight of a photoinitiator. The compositions are useful as 100% solids coatings and adhesives compositions which are curable upon exposure to radiation, and which are useful in a variety of applications such as for coating textiles and fabrics, for producing pressure sensitive adhesives, and for producing laminating adhesives.
