    摘要： The present invention relates to a method for producing an isocyanate-based polymeric material by polymerizing a reaction mixture which comprises different reaction components, including at least one polyisocyanate component and at least one component which is reactive towards said polyisocyanate component. The reaction components comprise at least one anchor component which has at least one anchor group which enables to bond a functional component covalently to the polymeric material. The anchor group is a reactive unsaturated group which does not react during the polymerization process so that the polymerization process is not interfered. The anchor group is selected to that it can bind the functional component by a click chemistry reaction to the polymeric material. It is more particularly selected so that it can participate in a catalyzed Huisgen 1,3-dipolar cycloaddition reaction or in a Diels-Alder cycloaddition reaction The invention also relates to the obtained isocyanate-based polymeric material, to the use thereof to produce a functionalized polymeric material and to this functionalized polymeric material.

    摘要： A process For the production of a thermoplastic polymer including carbon and sulphur in an atomic ration of C:S of at least 4 and at most 36 using thiol-ene addition polymerization, preferably with feedstocks obtained from renewable resources such as fatty acids from vegetable origin. The product is preferably aliphatic, meaning that at most 70% of the protons are present as aromatic hydrogen atoms and, if oxygen atoms are present in ester functions, the atomic ratio of the oxygen atoms present in ester functions relative to the number of sulphur atoms in the polymer is less than 1.0. The polymer may be used to produce a shaped article.

    摘要： Methods and systems are provided for a dry silicone gel. The dry silicone gel comprises a base polymer having a vinyl-silicone group and a crosslinker having thiol groups. The dry silicone gel may be made without the use of a catalyst by reacting the base polymer and crosslinker in the presence of a photo or thermal initiator. In some embodiments, the gel also comprises a chain extender having thiol groups. In certain embodiments, the dry silicone gel may comprise: (1) a hardness between 100 g and 300 g, (2) a stress relaxation between 30% and 60% when subjected to a deformation of 50% of the original size of the gel, (3) a compression set between 4% and 20% after 50% strain has been applied to the gel for 1000 hours at 70° C., and/or (4) less than 10% oil bleed out under compression of 1.2 atm after 60 days at 60° C.

    摘要： The invention relates to a method for functionalizing a thermoset, crosslinked isocyanate-based polymeric solid material which is made of isocyanate and isocyanate reactive components, at least one of which comprises an anchor component which has at least one anchor group. The anchor groups on the solid material are formed by terminal alkene and/or alkyne groups. To functionalize this polymeric solid material it is brought in contact with a solution which contains at least one functional component. This functional component comprises at least one thiol group and is allowed to bind covalently to the polymeric solid material by a free-radical addition reaction between the thiol groups on the functional component and the terminal alkene and/or alkyne anchor groups on the undissolved solid material. An effective functionalization of the polymeric material can thus be achieved notwithstanding the heterogeneous reaction conditions.
