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.

(Meth)acrylates are prepared in a single-step method from a mixture of (meth)acrylic acid and at least one biobased oil and/or its derivative(s), including at least one unsaturation. The (meth)acrylates are made by directly adding the (meth)acrylic acid to the biobased oil by reacting in the presence of an acid catalyst, including an inorganic or organic acid having at least one oxygen atom present thereon and which possesses at least one acid functionality having an ionization constant in water which is not greater than 3.

Methods of direct addition of (meth) acrylic acid to bio-based oils

Polymers, particularly those used in pressure-sensitive adhesives, are prepared from a mixture of structural isomers of a secondary alkyl (meth)acrylate monomer. The adhesives are characterized by exhibiting an overall balance of adhesive and cohesive characteristics and exceptional adhesion to low surface energy substrates.
