标 题:Synthesis of a dendritic polyalcohol
发明人：IHRE HENRIK; HULT ANDERS
权利人:PERSTORP AB; IHRE HENRIK; HULT ANDERS
摘要:A process for a double stage convergent synthesis of a polymeric polyalcohol substantially and preferably built up from polyester units and composed of a monomeric or polymeric core to which at least one hyperbranched dendritic branch (dendron) consisting of a number of branching generations is added. The branching generations comprise a polymeric or monomeric branching chain extender having three reactive functions of which two are hydroxyl groups and one is a carboxyl group. The two hydroxyl groups of the branching chain extender is in a first step ketal protected by reacting said two hydroxyl groups with a ketal. A second step includes protection of the carboxyl group of said branching chain extender. The ketal protected branching chain extender and the carboxyl protected chain extender are then employed for repeated addition in a number of step yielding a predetermined number of branching generations. The thus synthesized dendron is finally added to a core having reactive hydroxyl or epoxide groups and the ketal protected hydroxyl groups are optionally deprotected.

摘要:A process for synthesis of a polymeric polyalcohol substantially and preferably built up form polyester units and composed of a monomeric or polymeric initiator molecule to which at least one dentritic branch (dendron) consisting of a number of branching generations is added. The branching generations comprise a polymericor monomeric branching chain extender having three reactive functions of which two are hydroxyl groups. The two hydroxyl groups of the ranching chain extender is acetal protected by reaction between said two hydroxyl groups and an acetal-forming carbonyl compound, preferably an aldehyde. The acetal protected branching chain extender is then employed for addition to the initiator molecule of a first branching generation followed by an optional deprotection of the hydroxyl groups by decomposition of acetals and for addition in repeated steps of further branching generations. Additions of branching generations individually employ an acetal protected branching chain extender synthesized from the same or a different branching chain extender and/or acetal-forming carbonyl compound and addition of a branching generation is optionally followed by addition of a spacing generation.

摘要:The invention provides compounds containing the ring-opening products of ethylenically unsaturated cyclic carbonates for use in preparing hydrogel polymers, as well as methods for their preparation. A preferred method of the invention includes the reaction of nucleophilic compounds containing Si, F, N or O atoms, or combinations thereof, or latent moieties in the form of unsaturated or hydroxylated functional groups, with ethylenically unsaturated glycerol carbonate derivatives. The compounds and hydrogel polymers are useful for the preparation of contact lenses.
