The invention relates to compositions comprising a fiber material and a specific thermoplastic binder. The thermoplastic binder comprises at least one thermoplastic polyurethane polymer (A), wherein said thermoplastic polyurethane polymer (A) comprises a reaction product of (i) at least one polyester polyol and (ii) at least one polyisocyanate, optionally at least one diol (iii) which is different from the polyester polyol (i) is contained. The molar ratio of the NCO groups of said polyisocyanate (ii) to the sum of OH groups of said polyester polyol (i) and said optionally containing diol (iii) is less than 1.00:1. Said polyester polyol (i) comprises (a) at least one semi-crystalline polyester polyol having a melting point (T) of from 40 to 180&#xb0; C., and (b) at least one non-crystalline polyester polyol. Furthermore, the present invention relates to a fiber-reinforced composite comprising a cured thermosetting polyurethane polymer matrix reinforced by the composition according to the present invention. Moreover, a method for the manufacture of the fiber-reinforced composite according to the present invention and use of the composition or the fiber-reinforced composite in railway vehicles, automotive vehicles, aircraft vehicles, boats, space vehicles, motorbikes, bicycles, sporting goods, helmets, functional clothing, shoes, construction parts in bridges and buildings or wind turbine blades are described.

Compositions comprising a fiber material and a thermoplastic binder

Disclosed is a method for formation of block copolymers using a Single Electron Transfer Living Radical Polymerization (SET-LRP) process. The process can be used to form di and tri-block copolymers from vinyl monomers. In one embodiment the SET-LRP process comprises initially forming a macroinitiator using SET-LRP to form a first block of a di or tri-block copolymer and then using SET-LRP to form additional blocks of the copolymer. The produced block copolymers have very narrow polydispersity indexes and controlled molecular weights. The process permits incorporation of photoinitiators in any of the block formation reactions. The method also includes purification processes that result in a block copolymer having very low color making it useful in a variety of applications. In one application block copolymers prepared according to the present process can be used in hot-melt adhesives.

Photocrosslinkable block copolymers for hot-melt adhesives

A novel material, forming supramolecular structures below its transition temperature, which contains at least one C&#x2550;O and/or C&#x2550;S group and at least one N&#x2014;H, O&#x2014;H and/or S&#x2014;H group and wherein the material has the structureA(-X&#x2014;B)&#x2003;&#x2003;(1)wherein A, X, B and n are defined. Also a process for preparation of the material and uses thereof.

Material forming supramolecular structures, process and uses

The invention provides an isocyanate free UV curable hot melt composition which may be hardened upon exposure to UV radiation to provide a protective coating. The coating is particularly useful in wood-working and furniture applications.

UV curable coating composition

Solvent free, moisture curable reactive hot melt adhesives are prepared using an oxazolidine functional prepolymer and a polyfunctional isocyanate.

Reactive hot melt adhesive

Reactive hot melt adhesives with long open time and/or high green strength prepared by using an acrylic polymer component containing a high molecular weight acrylic polymer.

Reactive hot melt adhesives

Reactive hot melt adhesives compositions with long open time and/or high green strength are prepared by the use of urethane diols. These results are achievable at moderate/low application viscosity or low application temperature.
