  • Patent number: 7132459
    Abstract: The invention relates to a method for the production of polyurethane-based technical formed parts, commodity goods and objects, preferably consisting of (meth)acrylate containing isocyanate and hydroxy groups and at least 0.5 mMol/g reactive double bonds that can be determined using a DSC method. In a first step, a mixture of all starting constituents is produced and given a desired form using methods such as casting, pressing, rolling or extruding that are known per se in plastic engineering technology, whereby said mixture simultaneously or subsequently undergoes a non-radically triggered polyaddition reaction (urethane reaction) and a polyurethane substance is created in the form of a flexible, optionally elastic pre-form that can be deformed without any removal of said material. In a second step, the pre-form undergoes preferably mechanical shaping in addition to substantially emission-free hardening by means of radical polymerization of the free double bonds.
