Claim 0:
1. A method for synthesizing ethylene alkanoate-alkyl acrylate bipolymers comprising the steps of:
performing a semi-continuous emulsion polymerization of a combination of two monomers in a main reactor at a temperature between 75 and 82° C. under monomer starved feed conditions;
adding a pre-emulsion from a stirred feeding tank at a feeding rate between 0.001 and 0.009 kg·L−1·min−1; and
adding an initiator solution from a stirred tank at a feeding rate between 0.0002 and 0.0009 kg·L−1·min−1.
