Abstract
Various novel acetal- and aldehyde-containing monomers are prepared. They can be polymerized and copolymerized by conventional polymerization techniques. The polymers contain repeating units derived from one or more ethylenically or allylically unsaturated monomers containing an acetal group or aldehyde group and optionally one or more repeating units derived from ethylenically or allylically unsaturated monomers other than the acetal-containing or aldehyde-containing monomer such as ethylene, vinyl acetate, ethyl acrylate, butyl acrylate, 2-ethylhexyl acrylate, hydroxyethyl acrylate, hydroxypropyl acrylate, methyl methacrylate or acrylic acid. Aqueous emulsions of polymers containing the acetal-containing monomers and a hydroxy-containing monomer are useful as binders for nonwoven fabrics.
