Preparing poly(meth)acrylate, useful to prepare isocyanate-based coating, comprises functionalizing copolymer containing polymerizable (meth)acrylate monomer exhibiting hydroxyl functionality, in presence of orthoester-compound

摘要

Preparing a poly(meth)acrylate with at least two hydroxyl groups blocked by an orthoester, comprises functionalizing a copolymer containing at least one polymerizable (meth)acrylate monomer, which exhibits at least one hydroxyl functionality or its precursor, in the presence of at least one orthoester-compound at room temperature. An independent claim is included for a solution polymer produced by the method.
