The present invention relates generally to substrates for making polymers and methods for making polymers. The present invention also relates generally to polymers and devices comprising the same.

The formaldehyde-free binder for materials containing cellulose contains a hydroxy aldehyde resin polycondensed with an ammonium salt, the resin being obtained, in especially preferred embodiments, from glycerin, in situ, with the aid of hydrogen peroxide. A protein component consisting of animal blood is added. The binder is urea-free and can be used as a one-component or two-component binder. It binds materials such as wood, paper and other natural fibres to form high-quality composite material products.

The invention relates to a security pigment, comprising core-shell particles having a core based on an organic addition polymer, a shell based on an organic condensation polymer and a feature substance present in the core in finely dispersed or dissolved form, wherein the addition polymer is a three-dimensionally cross-linked duromer.

An amine-functionalized, crosslinked porous copolymer can be synthesized by linking 1,4-benzenediamine and pyrrole with p-formaldehyde in the presence of concentrated hydrochloric acid catalyst. The polymer is permanently microporous, with a BET surface area of 250 to 350 m.sup.2/g. Due to the high concentration of polar amines within its backbone, the polymer exhibits a CO.sub.2 uptake of 17.5 to 30 cm3/g at 298 K and 1 bar, but demonstrated a remarkably high selectivity for CO.sub.2 over N.sub.2 at 298 K. Dynamic breakthrough experiments indicate that this material is an effective adsorbent for selectively separating CO.sub.2 from a dry and wet gas mixture containing N.sub.2 for over 45 cycles without significant loss of performance. Furthermore, the polymer can be regenerated at room temperature after each cycle by a simple N.sub.2 flow.
