Radically hardening compounds with reduced softener uptake

摘要

Composition comprises: (a) at least one radically polymerizable monomer M; and (b) at least one polyurethane(meth)acrylate (PUMA), which is obtained by reacting a polyester polyol P with a diisocyanate and (meth)acrylic acid or (meth)acrylamide or a (meth)acrylate (I). Composition comprises: (a) at least one radically polymerizable monomer M; and (b) at least one polyurethane(meth)acrylate (PUMA), which is obtained by reacting a polyester polyol P with a diisocyanate and (meth)acrylic acid or (meth)acrylamide or a (meth)acrylate of formula (HO-A-(Y1-C(=O)-CH(=CH 2)-R 1>) n) (I). R 1>H or CH 3; A : (n+1) valent 1-6C hydrocarbon; Y1 : O or NR 2>; R 2>H or 1-6C monovalent hydrocarbon; and n : 1-3. An independent claim is also included for a hardened composition comprising the composition, obtained by the curing process.
