    • PURPOSE: An adhesive polyolefin resin composition is provided to improve adhesion with polyesters like polyethylene terephthalate, and to remarkably reduce manufacturing cost by using reaction extrusion. CONSTITUTION: An adhesive polyolefin resin composition comprises an olefin-based compound, 1-50 parts by weight of glycidyl methacrylate, 0.001-5 parts by weight of organic peroxide initiator. The olefin-based compound is one or more selected from group 50-100.0 parts by weight of polyethylene, 50-100.0 parts by weight of ethylene-methyl acrylate, and 1-30 parts by weight methyl acrylate. The polyethylene has the melt flow index of 1-20 g/10min, and the weight average molecular weight of 10,000-200,000.

    • The invention describes an emulsion polymer obtainable by polymerizing a mixture comprising a) 5 to 99.9% by weight of one monomer or of a multitude of monomers having a water solubility of 2% by weight at 20°C; and e) 0.1-95% by weight of at least one activator, wherein components a) to e) together add up to 100% by weight of the polymerizable constituents of the mixture, and the emulsion polymerization is characterized in that e1) the activator is a compound of the formula I in which the Rto Rand X radicals are each defined as specified in the description; and in that e2) the activator e) is incorporated into the emulsion polymer via covalent bonds. The emulsion polymer allows the formation of core-shell polymers with protected polymer-fixed activator, and can be used particularly advantageously to control the pot life of two-component or multicomponent systems, for example in adhesives, casting resins, floor coatings, materials for reactive plugs, dental materials or in sealant materials.
