Abstract
(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.
