A process for the preparation of compounds of formula (I) in which Z is hydrogen or --NHZ is an activated amine group capable of reacting with a surface, the groups R are the same or different and each is a straight or branched C.sub.1 -C.sub.4 alkyl group, preferably methyl, n is from 2 to 6, and X is a straight or branched C.sub.1-20 alkylene group, or X is a group of formula --(CH.sub.2 CH.sub.2 O).sub.b --, or --(CH.sub.2).sub.c --Ar--(CH.sub.2).sub.d -- where b is from 1 to 20, c and d are the same or different and each is from 0 to 5, and Ar is a para- or meta- disubstituted phenyl group (preferably a para-disubstituted phenyl group) which is optionally further substituted by one or more C.sub.1 -C.sub.4 alkyl groups, or an acid addition salt thereof or a hydrate thereof, new compounds of formula (I) and salts and hydrates thereof and the use of compounds of formula (I) and salts and hydrates thereof in treating surfaces to render them more biocompatible.
一种用于制备具有式(I)化合物的方法,在该式中Z为氢或—NHZ为能够与表面反应的活化胺基团,基团R相同或不同,每个都是直链或支链C.sub.1-C.sub.4烷基基团,优选为甲基,n为2至6,X为直链或支链C.sub.1-20烷基基团,或X为式—(CH.sub.2 CH.sub.2 O).sub.b—的基团,或—(CH.sub.2).sub.c—Ar—(CH.sub.2).sub.d—其中b为1至20,c和d相同或不同,每个为0至5,Ar为对位或间位二取代苯基团(优选为对位二取代苯基团),可以进一步被一个或多个C.sub.1-C.sub.4烷基基团取代,或其酸加合物盐或水合物,新的式(I)化合物及其盐和水合物以及利用式(I)化合物及其盐和水合物在处理表面以使其更具生物相容性的方法。
