A curable composition comprising (A) an epoxy resin containing on average more than one epoxy group per molecule; (B) a compound of formula A[&#x2014;X&#x2014;CO&#x2014;CH&#x2014;CN](1), wherein A is hydrogen or C-Calkyl which is unsubstituted or substituted by one or more C-Calkoxy groups, C-Calkylcarbonyl groups, C-Carylcarbonyl groups, hydroxyl groups, amino groups, C-Calkylamino groups, C-Cdialkylamino groups, cyano groups or halogen atoms, or A is a bivalent aliphatic, cycloaliphatic, aromatic, araliphatic or heterocyclic organic radical, X denotes &#x2014;O&#x2014;or &#x2014;NR&#x2014;, wherein Ris hydrogen or C-Calkyl which is unsubstituted or substituted by one or more C-Calkoxy groups, C-Calkylcarbonyl groups, C-Carylcarbonyl groups, hydroxyl groups, amino groups, C-Calkylamino groups, C-Cdialkylamino groups, cyano groups or halogen atoms, n is 1 or 2; and (C) a protected base in the form of an adduct or salt which is able to release a basic compound upon heating to a temperature greater than 70&#xb0; C., is storage-stable, allows processing over a longer period of time (pot-life) and produces cured products having outstanding mechanical and thermal properties.

Latent curing accelerators

The present invention provides methods and apparatus for coating surfaces with specially designed thioethers and amphiphilic thioethers that reduce protein adsorption and/or cell adhesion. This reduction may be achieved, for example, by controlling the spacing or length of pendant chains or hydrophilic blocks in an amphiphilic thioether. Techniques for determining spacing include adsorbing the thioether from a solution or a colloidal suspension, or controlling the degree of polymerization of the thioether. Techniques for controlling the length of the pendant chains include controlling the degree of polymerization of the pendant chains. Multiblock copolymers of poly(propylene sulfide) and poly(ethylene glycol) ('PPS-PEG') represent an exemplary family of amphiphilic thioethers. Methods for coating surfaces with amphiphilic thioethers are also provided.

Coating hydrophobic surfaces with amphiphilic thioethers to reduce protein adsorption and cell adhesion

The invention provides methods for the preparation of multiblock copolymers, dispersions of multiblock copolymers, vesicles and micelles containing multiblock copolymers, and oxidative degradation products of multiblock copolymers.
