  The invention relates to a silane or silane mixture obtainable by reacting a hydrolysable silane of the formula (A): SiR4 in which R is a hydrolytically condensable group or hydroxyl with a compound R*(OH)x where x is 1, 2, 3 or greater 3, where R* has a straight-chain or branched hydrocarbon skeleton which, according to the number x, is monovalent, divalent, trivalent or multivalent, and has a hydrocarbonaceous chain interrupted by at least two —C(O)O— groups, wherein there are a maximum of 8 successive carbon atoms in the individual hydrocarbon units formed by interruptions within this chain and the, or in the case of branched structures at least one, end of the hydrocarbonaceous chain at the opposite end to the sole hydroxyl group or one of the hydroxyl groups bears an organically polymerizable group, wherein the alcohol is otherwise unsubstituted or has further substituents. The invention further relates to an organically modified silica polycondensate formed as a result of hydrolytic condensation of the silane or silane mixture and optionally a subsequent organic polymerization of the organically polymerizable groups, with optional addition of an organic, at least difunctional compound to the silica polycondensate prior to the organic polymerization.

  该发明涉及一种硅烷或硅烷混合物，其可通过将具有以下式(A)的可水解硅烷与化合物R*(OH)x反应而得到：SiR4，其中R是一个可水解缩聚基团或羟基，化合物R*具有直链或支链烃骨架，根据数目x，该骨架是一价、二价、三价或多价的，并且具有至少两个—C(O)O—基团中断的烃链，其中在该链内由中断形成的各个烃单元中最多有8个连续的碳原子，或者在支链结构的情况下，至少有一个烃链的末端，与唯一的羟基或其中一个羟基相对的末端具有一个有机聚合基团，其中醇在其他方面未被取代或具有进一步的取代基。该发明还涉及一种有机改性的二氧化硅缩聚物，其是由硅烷或硅烷混合物的水解缩聚以及有机聚合基团的随后有机聚合形成的，有机聚合之前在有机聚合之前向二氧化硅缩聚物中添加有机的至少二官能化合物。

  The present invention provides modified multifunctional thiol-ene monomers wherein one or more thiols are reacted with a Michael addition reactive double bond compound. The present invention further discloses photocurable thiol-ene formulations comprising thiol-ene monomers including the modified multifunctional thiols. The present invention further discloses photocurable thiol-ene formulations comprising thiol-ene monomers and Michael addition reactive double bond molecules and a Michael catalyst. The formulations of the present invention can be photocured to make films or coatings. In a further disclosure, the formulations, including those comprised of unmodified multifunctional thiols and multifunctional enes, are photocured to form films applied to non-flexible or flexible polymer or non-polymer substrates suitable for food packaging, electronic products, optical products and other applications and free-standing films. The present invention further discloses photocurable thiol-ene formulations comprising thiol-ene monomers and Michael addition reactive double bond molecules and a Michael catalyst. These formulations are disclosed to form free-standing films and coatings on substrates when applied to flexible substrates. Such materials are suitable for use in the packaging of food products and other products which are to be maintained in a hermetically sealed relationship to the atmosphere.
