The present invention concerns a process for the preparation of a copolymer comprising the steps of copolymerizing under suitable reaction conditions at least one first type of olefin monomer and at least one second type of functionalized olefin monomer using a catalyst system to obtain a polyolefin main chain having one or multiple functionalized short chain branches, the catalyst system comprising: i) a single-site catalyst or catalyst precursor comprising a metal selected from Ti3+ or Cr3+; ii) a co-catalyst; iii) optionally a scavenger.

An aqueous emulsion is made by emulsion polymerizing at least one free-radically polymerizable monomer and one or more di- or higher-functional chain-extending monomers in the presence of an aqueous solution of an oligomer made from a mixture of free-radically polymerizable monomers including acid-functional free-radically polymerizable comonomers, adhesion-promoting free-radically polymerizable comonomers and other free-radically polymerizable comonomers. The aqueous emulsion is substantially free of adipic dihydrazide, has a minimum film forming temperature55 C., and on drying has a Koenig hardness of at least 40 sec.
