摘要:
Combination compounds from curing agents/accelerators and flame-protection agents for the latent curing/acceleration of epoxide resin systems and their endowment with flame-retarding properties, the epoxide resin systems being able to be thermally cured, as well as the products prepared from the epoxide resin systems.
摘要:
Modified phenolic resins and processes for producing these are described, as also are phenolic-resin formulations which comprise the modified phenolic resins, and processes for producing these. Specific uses of appropriate phenolic resins and, respectively, phenolic-resin formulations, and the use of block copolymers for producing phenolic resins, are also described.

摘要:
The invention relates to a polymeric composition containing: a) at least one epoxy resin; b) at least one copolymer with groups, which react with epoxy resins, and with a glass transition temperature Tg of −20° C. or lower, c) nanoparticles having a mean particle size dmax ranging from 5 to 150 nm that is measured by means of a small-angle neutron scattering (SANS). The inventive composition enables the production of adhesives, composite materials, coatings and casting compounds exhibiting improved mechanical properties, particularly improve impact strength.
摘要:
The invention provides a polymeric composition comprising: a) at least one resin selected from the group consisting of vinyl ester resins, unsaturated polyester resins, acrylates and methacrylates, b) at least one copolymer having resin-reactive groups and a glass transition temperature Tg of −20° C. or less, c) nanoparticles having an average particle size dmax as measured by means of small-angle neutron scattering (SANS) of 5 to 150 nm. The compilation according to the invention allows the production of composite materials, coatings, casting compositions, adhesives, and dental materials which have enhanced mechanical properties, particularly enhanced impact strength.
