PRESSURE SENSITIVE COMPOSITIONS BASED ON A MODIFIED RUBBER POLYMER AQUEOUS DISPERSION |
摘要 |
The invention relates to an aqueous polymer dispersion which comprises : a) an aqueous polymer dispersion comprising grafted rubber polymeric particles from rubber polymer being selected from natural or synthetic rubber, b) an aqueous polymer dispersion with polymeric particles of a second polymer comprising monomeric units derived from a monomeric composition b) comprising : b1) a (meth)acrylate of a linear or branched alcohol in C4 to C10 or a mixture of such (meth)acrylates, said (meth)acrylate having Tgb1 lower than -30°C, b2) optionally, at least one comonomer having Tgb2 higher than -30°C, with said grafted rubber polymeric particles being grafted in an aqueous dispersion by a part of said monomeric composition b) as defined above. The invention covers also a specific process of preparation of said dispersion, an adhesive composition comprising said dispersion, the use of said dispersion in pressure sensitive adhesives and the resulting adhesive. |
