Abstract: Provided are multistage polymers that comprise (i) a first stage comprising a first copolymer having a first theoretical Tg, the first copolymer being derived from a soft ethylenically-unsaturated monomer, a phosphorus-containing monomer, and an acetoacetoxy monomer; and (ii) a second stage comprising a second polymer having a second theoretical Tg, the second polymer being derived from one or more hard ethylenically-unsaturated monomers. The multistage polymers can be in the form of multilayer particles that comprise (i) a first layer comprising the first copolymer; and (ii) a second layer surrounding at least a portion of the first layer comprising the second polymer. Also provided are aqueous compositions including one or more of the multistage polymers (or multilayer particles) described herein, as well as methods for making the multistage polymers (or multilayer particles) described herein.

Abstract: An adhesively sealed product is disclosed comprising a first surface, a second surface, and an adhesive layer bonding said first surface to said second surface; said adhesive layer comprising a copolymer and a protective colloid, the copolymer being derived from monomers including one or more a C1 to C20 alkyl(meth)acrylates and having a glass transition temperature (Tg) of from −40° C. to 0° C. using differential scanning calorimetry (DSC), wherein opening the product by separating the first surface from the second surface results in adhesive failure of the adhesive layer thereby resulting in a reclosure adhesion of less than 0.5 N/15 mm. A method of producing an adhesively sealed product is also disclosed.
