Abstract (en)

[origin: WO2011051206A1] The invention relates to a contact adhesive comprising a mixture of two polymers P1 and P2 formed of two radically polymerizable monomers, wherein P1 is formed of a first main monomer M1 at at least 50 wt %, comprising, when polymerized as a homopolymer, a glass transition temperature of less than 0°C, and wherein P2 is formed of a second main monomer M2 at at least 50 wt %, comprising, when polymerized as a homopolymer, a glass transition temperature of less than 0°C, and being different from M1. P2 is otherwise formed by M1. The polymerization of P2 takes place by stage polymerization, wherein a monomer composition comprising M2 is polymerized in a first stage, and a monomer composition comprising M1 is polymerized in a second stage.
