    摘要： The present invention is concerned with a new class of compounds prepared by reacting cyclic aminals of the formula ##STR1## with polyisocyanates of the formula R.sub.5 (NCO).sub.m+n to yield ##STR2## and with this process for obtaining said compounds, as well as the use of such compounds in polyurethane chemistry. If such compounds are free of isocyanates (n=0) they are useful as latent cross-linkers or hardeners activatable by heat or moisture. If such compounds carry free isocyanate groups (n=1 or 2) there are useful as synthetic resin precursors. In the above formulaem represents an integer of from 1 to 3, andn represents 0, 1 or 2, and the sum of m+n is 2 or 3,R.sub.1 represents an aliphatic hydrocarbon group which is optionally cyano-substituted and which has from 1 to 6 carbon atoms, a cycloaliphatic hydrocarbon group having from 5-10 carbon atoms or an araliphatic hydrocarbon group having from 7-10 carbon atoms;R.sub.2 represents a divalent aliphatic hydrocarbon group having from 2 to 6 carbon atoms, at least two carbon atoms being situated between the two nitrogen atoms;R.sub.3 and R.sub.4 are identical or different and represent hydrogen, aliphatic hydrocarbon groups having from 1 to 18 carbon atoms, cycloaliphatic hydrocarbon groups having from 5 to 10 carbon atoms or aromatic hydrocarbon groups having from 6 to 10 carbon atoms, or the two groups R.sub.3 and R.sub.4 together with the carbon atom of the heterocyclic ring may also form a 5-membered or 6-membered cycloaliphatic ring; andR.sub.5 represents an (m+n)-valent group such as that which can be obtained by the removal of m+n isocyanate groups from an (m+n)-valent polyisocyanate.

    摘要： A process for encapsulating products in a polymer by interfacial polymerization, in which a stabilized dispersion of droplets of a first liquid which is to be encapsulated or a stabilized dispersion of solid particles which are to be encapsulated is formed in a continuous phase of a second liquid, and wherein one of the two capsule wall-forming reaction components is present in free form while the other of the two capsule wall-forming reaction components is present in reversibly blocked form, both reaction components are present in the first or second liquid without reacting with one another and the reaction component which is present in reversibly blocked form is deblocked by means of water present in the second or first liquid and then reacts with the reaction component present in free form to form a polymeric capsule wall, the droplets of the first liquid or the solid particles being encapsulated in small capsules consisting of polymeric material.
