A halogen-free flame retardant adhesive comprises an acrylic copolymer preparable by polymerization of monomers comprising a first monomer which comprises a low glass transition temperature (Tg) monomer, a second monomer which comprises a high Tg monomer, wherein at least one of the first and second monomers comprises a (meth)acrylate, and a phosphinate containing monomer.

Halogen-free flame retardant pressure sensitive adhesive and tape

Polymers, particularly those used in pressure-sensitive adhesives, are prepared from a mixture of structural isomers of a secondary alkyl (meth)acrylate monomer. The mixture is made by dehydrating a biobased C-Calcohol with a first acid catalyst using a continuous process to form a mixture of olefins, and reacting (meth)acrylic acid with at least some of the mixture of olefins in the presence of a second acid catalyst. The adhesives are characterized by exhibiting an overall balance of adhesive and cohesive characteristics, and containing biobased material.

Method for preparing (meth)acrylates of biobased alcohols and polymers thereof

A method of making 2-octyl acrylate comprising reacting 2-octanol with acrylic acid in the presence of an acid catalyst and added water is described. The 2-octanol may be derived from renewable resources, such as castor oil. The method is efficient and provides selectivity for 2-octyl acrylate.
