摘要:
The present invention relates to polyester acrylate graft copolymers comprising poly(meth)acrylates as graft substrate, the graft substrate having internal and/or terminal functional groups and polyester side chains as graft branches and/or having polyester blocks attached to at least one chain end of the graft substrate. The present invention further relates to processes for preparing the polyester acrylate graft copolymers and also to their use.
摘要:
The present invention relates to the use of mixtures comprising polymer types A, B and AB as or in adhesives, polymer type A being a copolyester prepared with cocondensation of unsaturated aliphatic dicarboxylic acids, polymer type B being a (meth)acrylate homopolymer and/or copolymer, and polymer type AB being a graft copolymer of polymer type A and polymer type B.

摘要:
The invention relates to a process for preparing polymers for coating applications by polymerizing esters of acrylic acid or of methacrylic acid or vinyl aromatics or other free-radically polymerizable vinyl compounds or monomer mixtures composed predominantly of such monomers by means of a continuous polymerization process. In particular, the invention relates to a solvent-free preparation process for polymers, through which the binder can be prepared for coating applications with superior processing properties, very good thermal stability, improved pigment wetting and a higher gloss.
