    摘要： The present invention relates to a method of preparing a pressure-sensitive adhesive comprising the steps of: (i) providing an essentially solvent-free mixture comprising one or more free radically polymerizable monomers having one ethylenically unsaturated group and at least one free-radical polymerization initiator, (ii) partially polymerizing said mixture to provide a partially polymerized mixture exhibiting a Brookfield viscosity of between 1,000 and 125,000 mPa·s at 20° C. and a degree of conversion of monomers to polymer of between 30-60 wt. % with respect to the initial mass of the monomers prior to polymerization, (iii) adding one or more free-radical radiation polymerization initiators to the partially polymerized mixture to provide a radiation-curable precursor, (iv) applying the radiation-curable precursor to a substrate, and (v) further polymerizing the radiation-curable precursor by subjecting it to actinic irradiation to provide said pressure-sensitive adhesive.

    摘要： A process for crosslinking a melt-processed polymer composition comprises the steps of (a) forming a polymerizable mixture comprising (i) at least one monoethylenically-unsaturated monomer or prepolymer and (ii) at least one monoethylenically-unsaturated, blocked mono- or polyisocyanate that is thermally stable at a selected melt processing temperature range and that is thermally deblockable at and above a deblocking temperature that is higher than the selected melt processing temperature range; (b) exposing the polymerizable mixture to transmissive energy to polymerize the mixture to form a polymer composition comprising polymerized units derived from the blocked mono- or polyisocyanate; (c) melt processing the polymer composition at the selected melt processing temperature range to form a melt-processed polymer composition; and (d) during melt processing or thereafter, increasing the temperature of the melt-processed polymer composition to the deblocking temperatures in the presence of at least one isocyanate-reactive crosslinking agent, to effect crosslinking of the melt-processed polymer composition.
