摘要:The invention concerns new types of porous coordination polymers (MOF) and a method for their preparation. MOFs have been prepared through synthesis of salts of trivalent cations M 3+ , the source of which are aluminium, chromium, iron or yttrium salts, it is advantageous if of chlorides, nitrates or sulphates, with linkers carrying two or more phosphinic groups under presence of solvent. Linkers are phenylene-1,4-bis(R phosphinic acid) (PBPA) and biphenylene-4,4′-bis(R phosphinic acid) (BBPA). For the prepared MOFs, the structure has been tested using x-ray powder diffraction, specific surface and porousness which have been characterised through adsorption isotherm of nitrogen and further the stability of prepared MOFs has been determined using thermogravimetric analysis. n All the prepared MOFs have been stable around 400° C. and have contained mesopores or micropores where hydrogen or CO 2 , for example, can be stored.

摘要:Provided are a preparation method of an epoxy compound having an alkoxysilyl group in which an increase in the epoxy equivalent weight (EEW) of the epoxy compound is minimized because alkoxysilylation occurs through a simple one-step reaction using a hydroxyl group formed during the synthesis of the epoxy compound, an epoxy compound having an alkoxysilyl group prepared by the method, a composition comprising the same, and a use thereof. The method includes the reaction of an epoxy compound having a hydroxyl group with an isocyanate alkoxysilane in the presence of amine-based base catalyst, wherein the epoxy compound having an alkoxysilyl group has a mole ratio of [epoxide group]:[alkoxysilyl group] of n:1 ranging from 2:1 to 10:1, and an EEW increase of the epoxy compound having an alkoxysilyl group is less than 260/n. The epoxy compound has good physical properties when being cured.
