Abstract
Abstract A novel acrylic-siloxane paint binder resin that is crosslinkable with vinyl monomers by exposure to an electron beam is produced in a three step reaction wherein (1) a siloxane having two or more hydroxy or alkoxy functional groups per molecule is reacted with a C5 - C12 monohydroxy acrylate, i.e., the monohydroxy ester of a C2 - C8 diol and acrylic or methacrylic acid, (2) the siloxane-acrylate product of the first reaction step is reacted with a mixture of vinyl monomers at least one constituent monomer of which is selected from glycidyl acrylate and glycidyl methacrylate, and (3) the resultant siloxane-acrylate-vinyl monomer copolymer is reacted with a C5 C12 monohydroxy acrylate, i.e., the monohydroxy ester of a C2 C8 diol and acrylic or methacrylic acid.
