Emulsion polymer of heterogeneous molecular weight and preparation thereof |
摘要 |
Disclosed is a polymer and its preparation by reacting part of the monomers in the reactor in such a way as to obtain a high molecular weight product, and reacting at least one other portion of the monomer in the same reactor in such a way as to obtain at least one low molecular weight fraction. The products are useful in contact adhesives, particularly when blended with an aminoplast or phenoplast as a tackifier and crosslinker, and with a thickening agent such as polyvinyl alcohol.
