摘要:
The present invention accordingly provides new organopolysiloxanes having (meth)acrylic ester groups attached pendent and terminally or only pendent via SiOC groups, of the general average formula (I) and also provides a process for preparing the compounds by reacting polysiloxanes containing SiH groups with (meth)acrylated monoalcohols and/or (meth)acrylated polyalcohols using Lewis-acidic catalysts or catalysts comprising a carboxylic acid and salts thereof.
摘要:
The invention relates to the use of polyethers containing urethane or urea groups as foam stabilizers, obtained by reacting at least one isocyanate with (a) at least one hydrophilic polyether which statistically carries at least one OH and/or NH2 and/or NH function and (b) at least one hydrophobic polyether which statistically carries at least one OH and/or NH2 and/or NH function and optionally (c) further compounds which carry at least one OH and/or NH2 and/or NH function and/or other isocyanate-reactive groups, such as carboxyl or epoxide functions, with the proviso that at least one isocyanate is ≧difunctional.

摘要:
The invention relates to the use of substantially silicon-free polymers, obtainable by free radical graft polymerization of up to 50 parts by weight of at least one ethylenically unsaturated monomer (A) in the presence of at least 50 parts by weight of at least one polyether (B), as stabilizers for the preparation of PU and/or PI foams.
