New synthetic resin based on poly(meth)acrylate-urethane-(meth)acrylate, obtained by polymerizing (meth)acrylate monomers with/without isocyanates, useful in the production of radically hardenable composition and as binders

摘要

Synthetic resin based on poly(meth)acrylate-urethane-(meth)acrylate in urethane(meth)acrylates, obtained by: (a) producing (meth)acrylate monomers (I) exhibiting no reactive isocyanates groups, and (meth) acrylate monomers (II) exhibiting reactive isocyanate groups; (b) polymerizing (I) and (II) to poly(meth)acrylate (III); (c) reacting (III) with an isocyanate compound (IV); and (d) converting the obtained composition with (II), is new. Synthetic resin based on poly(meth)acrylate-urethane-(meth)acrylate in urethane(meth)acrylates, obtained by: (a) producing (meth)acrylate monomers (I) exhibiting no reactive isocyanates groups, and (meth) acrylate monomers (II) exhibiting reactive isocyanate groups; (b) polymerizing (I) and (II) to poly(meth)acrylate (III), which exhibits reactive isocyanates groups; (c) reacting (III) with an isocyanate compound (IV) exhibiting more than one isocyanate group, in which 5-40% isocyanate groups of the isocyanate compound reacted with compounds with reactive isocyanate groups; where partial cross-linking of (III) takes place under the increase of weight by means of molecular weight around factor 2-20, in which (IV) reacts respectively with more than one of its isocyanates groups with more than a given (III); and (d) converting the obtained composition with (II), is new. Independent claims are included for: (1) radically hardenable composition comprising synthetic resin; (2) a composite active substance or composite active part comprising a radically hardenable composition in hardened form; (3) a preparation of a composite active substance or composite active part, comprising subjecting a radically hardenable composition to hardening; (4) a lacquer comprising a radically hardenable composition; and (5) a preparation of a hardened lacquer, comprising subjecting radically hardenable composition to hardening.
