摘要： The combination of adhesion and rheology properties of aqueous adhesives the adhesive component of which is a water soluble or water swellable polymeric material can be improved by copolymerizing the monomers from which the polymeric material is obtained with an ethylenically unsaturated monomer that includes a pendant group --A.sub.m B.sub.n A.sub.p R where B is ethoxy, n is at least 2, A is propoxy or butoxy, m and p are each less than n and are preferably zero, and R is a hydrophobic group.

摘要： A polymer of an ethylenically unsaturated monomer containing a pendant hydrophobic group and, optionally, other monomers such as (meth) acrylic acid, ethyl acrylate or acrylamide is provided as a stable, substantially anhydrous dispersion containing at least 40% by weight of the polymer in a continuous phase of a non-aqueous liquid. The polymer in the dispersion generally includes acid groups and is neutralized, preferably with ammonia or a volatile amine. The dispersion can be made by reverse phase polymerization of an aqueous blend of monomers, followed by dehydration, or by making the polymer from a water insoluble blend of monomers by oil in water emulsion polymerization, dispersing the resultant oil in water emulsion into the non-aqueous liquid, and then dehydrating. The monomer including the hydrophobic group is preferably an allyl ether.
