An isocyanate-terminated prepolymer C having an NCO content of from &#x2267;26% by mass to &#x2266;31.0% by mass is obtainable from the reaction of an isocyanate composition A having a viscosity at 25&#xb0; C. of from &#x2267;60 mPas to &#x2266;800 mPas, comprising from &#x2267;25% by mass to &#x2266;60% by mass MDI and from &#x2267;40% by mass to &#x2266;75% by mass pMDI, wherein the sum of the amounts of those components is &#x2266;100% by mass, with a bifunctional polyester ether polyol B having an OH number of &#x2267;200 mg(KOH)/g and &#x2266;500 mg(KOH)/g, obtained from the reaction of a dicarboxylic acid/dicarboxylic acid derivative with at least one polyol and with an epoxide, wherein the polyester ether polyol B is used in amounts of from &#x2267;1.5% by mass to &#x2266;6.0% by mass, based on the sum of the masses of A and B. The invention further provides a PUR/PIR polymer produced from the prepolymer C, its use and composite elements based thereon.

Lightly modified prepolymers and uses thereof

The present invention relates to the technical field of isocyanates. The present invention provides a method for preparing NCO prepolymers by reacting a stoichiometric excess of an organic isocyanate with an isocyanate-reactive component, the reaction components being mixed together and the mixture being introduced directly into a storage or transport vessel, where it reacts to completion.

The present invention relates to high-quality polyurethane and polyurethane urea elastomers which exhibit unique combinations of processing characteristics, oxidation resistance, mechanical and mechanical/dynamic properties in particularly demanding applications. These polyurethane elastomers and polyurethane urea elastomers are based on novel polycarbonate polyols.

Polyurethane and polyurethane urea elastomers based on polycarbonate polyols

Polyurethane prepolymers are described which are prepared from 2,4'-diiso-cyanate diphenylmethane (2,4&#x2032;-MDI), a polyol component and an aliphatic diisocyanate. These prepolymers can be cured with aliphatic, cycloaliphatic and/or aromatic amines to form a cured urethane elastomer. In comparison to cured urethane elastomers based on monomeric 2,4&#x2032;-MDI, these prepolymers provide elastomers with extended pour life, i.e. they exhibit a slower rate of viscosity buildup after curative and prepolymer are mixed which results in a reduced propensity to crack during the curing process and gives the opportunity to cast larger parts. In comparison to polyurea/urethanes prepared from cured TDI-prepolymers and which optionally include H12-MDI, the prepolymers of the invention have better health and safety aspects.

Polyurethanes cured with amines and their preparation

Isocyanate mixtures comprising: (a) NCO prepolymers having an NCO content of 1.5 to 18 wt. %; and (b) 1 to 40 wt. % of monomeric 2,2'-diisocyanatodiphenylmethane, based on the isocyanate mixture; wherein the isocyanate mixture has a total NCO content of from 2 to 22 wt. %; polyisocyanate polyaddition products prepared therefrom; and methods of making the same.

A method and system for efficiently coding test pattern for ICs in scan design and build-in linear feedback shift register (LFSR) for pseudo-random pattern generation. In an initialization procedure, a novel LFSR logic model is generated and integrated into the system for test data generation and test vector compression. In a test data generation procedure, test vectors are specified and compressed using the LFSR logic model. Every single one of the test vectors is compressed independently from the others. The result, however, may be presented all at once and subsequently provided to the user or another system for further processing or implementing in an integrated circuit to be tested. According to the present invention a test vector containing 0/1-values for, e.g., up to 500.000 shift registers and having, e.g., about 50 so called care-bits can be compressed to a compact pattern code of the number of care-bits, i.e., 50 bits for the example of 50 care-bits.

Method and system for coding test pattern for scan design

A plurality of pseudo random bit-pattern generators (PRPGs), advantageously linear feedback shift registers (LFSRs), having predetermined lengths and individual different tap locations for providing a respective sequence of pseudorandom bit-patterns. An output from a predetermined respective tap location at each LFSR is fed to a common OR-gate, a selected subset of the LFSRs are initialized with all bit storing locations to '0' in order to generate a respective permanent '0'-bit sequence, and the output of the OR-gate is used for reading the weighted or flat random bit output-pattern thereof. By controlling the number of zero-set LFSRs&#x2014;a subset of the LFSRs&#x2014;the weight of the generated output-pattern can be controlled.
