The invention is directed to an antimicrobial polymer that can preferably be processed thermoplastically, a method for the preparation of said antimicrobial polymer and its use in antimicrobial treatment. The invention is further directed to polymer blends containing antimicrobial polymers and the use of special monomers in the preparation of antimicrobial polymers that can be processed thermoplastically.

Antimicrobial polymer

The present invention relates to a radically curable chemical composition in the form of a resin for the production of materials with an intrinsically antimicrobial effect, as well as a process for the production of such resins and materials, as well as the use of an amino-functionalized styrene derivative as reactive diluents. The cross-linked plastic formed upon curing has an intrinsically antimicrobial effect without the use of additional biocides.

Cross-linked plastic material with an intrinsic antimicrobial effect based on unsaturated polyesters

A standard calibration set having at least three calibration standards. Each standard is a molded article made of a thermoplastic polymer which contains the elements Cd, Cr, Pb, Hg and Br, with the Cr:Pb:Hg:Br:Cd ratio being different in each of the three calibration standards. Further disclosed is a method for manufacturing the calibration standards and their use in X-ray fluorescence analysis.

Set of calibration standards

Catalysts contain, as structural units, at least one tertiary amino group and at least one group which, after its decomposition, is capable of complexing or protonating the tertiary amino group.

Catalysts, in particular for the preparation of polyisocyanate polyadducts

The invention relates to polyurethane foams comprising

Modified polyurethane foamed materials used as adsorbents

The present invention relates to a mixture that contains (i) at least one isocyanate and (ii) at least one organic and/or inorganic acid anhydride.

Mixture containing isocyanates as well as organic and/or inorganic acid anhydrides

The polyisocyanate polyaddition products comprise hydrophobic compounds plus at least one further compound selected from the group consisting of: (i) organic, cyclic compounds having a molecular weight of from 200 to 3000 g/mol, (ii) salts of metals of transition groups I, II and/or VIII, (iii) organic and/or inorganic acid anhydrides, (iv) cyclic sulfonic esters and/or sulfones, (v) lactones, lactams and/or cyclic esters and/or (vi) &agr;,&bgr;-unsaturated carboxylic acids, &agr;,&bgr;-unsaturated carboxylic acid derivatives, &agr;,&bgr;-unsaturated ketones and/or &agr;,&bgr;-unsaturated aldehydes.

Polyisocyanate polyaddition products

In a process for preparing polyisocyanate polyaddition products by reacting isocyanates with compounds which are reactive toward isocyanates, in the presence or absence of blowing agents, catalysts, auxiliaries and/or additives, the reaction is carried out in the presence of (i) particles which have a size of <200 &mgr;m and a melting point in a range from 50 to 300&deg; C., or in the presence of thermoset particles (ii) or in the presence of particles (i) and (ii).
