Abstract
New vinylidene chloride copolymer latexes have been prepared with a hydroxyalkyl ester comonomer and acrylamido-2-methylpropane sulfonic acid. These products can be used to coat unprimed polyolefin film and yield laminates having dynamic peel strengths as high as 2400 g/in, that is equivalent to or greater than the peel strength of laminated uncoated polyethylene film itself.
