摘要： A method of forming a three-dimensional object comprises the steps of forming a layer of a particulate composition, selectively depositing a liquid composition onto the layer of the particulate composition in accordance with computer data corresponding to the shape of at least a portion of a three-dimensional object, and repeating the steps a plurality of times to form a three-dimensional object. The particulate composition comprises a plurality of first particles that comprise a resin component comprising a first resin, the first resin comprising a first resin polymerizable group. Either or both of the particulate composition and the liquid composition comprise an initiator capable of initiating polymerization of at least the first resin. At least the first resin undergoes melting and polymerization in a plurality of the locations where the liquid composition has been selectively deposited.

摘要： The present invention relates to a polymer composition with an increased rate of oxygen- uptake by the presence of an oxidation catalyst. The invention further relates to a process to increase the rate of oxygen-uptake by a polymer composition. The invention also relates to a process to increase the oxo- biodegradability of a polymer composition and to the use of such a composition for the preparation of a product having a controlled lifetime. The invention further relates to a process to increase the rate of oxygen-scavenging in a composition containing a carbon-containing polymer, the composition obtained by this method and its use in the preparation of an oxygen-scavenging product. The present invention further relates to objects containing an oxygen scavenging layer containing such a composition.

摘要： The present invention relates to resin compositions for radical curing comprising a component (I) containing reactive carbon-carbon unsaturations and a component (ll) containing XH-groups, with X not being C or O., which resin compositions (a) are substantially free of photoinitiators; (b.) have an average number of reactive carbon-carbon unsaturations of component (I) higher than 2; (c) have an average number of XH-groups of component (II) equal to or higher than 2, with at least one of the XH-groups of the XH-component being a thiol group, and; (d) whereby at least one of the average numbers of (b) and (c) is higher than 2; (e) and at most 5 mol% of the reactive unsaturations is capable of undergoing homopolymerisation; (f) respectively is present in the form of a mono-ene functional alkylene; and (g) the molar ratio of the XH-groups and of the reactive unsaturations is in the range of from 4 : 1 to 1 : 4; with the proviso that the RU component is not tris-(norborn-5-ene-2-carboxy) propoxypropane. The present invention also relates to processes for curing such resin compositions, in particular by cold curing. And finally, the present invention also relates to a new process for the synthesis of Diels-Alder adducts of cyclopentadiene and a resin component containing telechelic carbon-carbon unsaturation. The resin compositions are capable of providing constructive materials with tack-free surfaces by fast, and tunable, radical curing, and without any problems of so-called oxygen inhibition. Suitable applications are in chemical anchoring, roofing, flooring, (re)-lining, SMCs and BMCs.
