Abstract
The present invention relates to waterborne polymer compositions comprising a polymer obtained with recycled monomers, said recycled monomers comprising specific chemical compounds at specific levels. The present invention also relates to a process for producing said polymer composition. The use of the waterborne polymer compositions in coating, paint, primer, ink, pressure sensitive adhesive, or varnish is also a part of the present invention.
Claims19
A waterborne polymer composition, comprising a polymer obtained from 1 to 100% by weight of at least one recycled monomer, wherein the recycled monomer comprises from 500 ppm to 30.000 ppm by weight of methyl isobutyrate.
A process for producing a waterborne polymer composition, comprising the step of polymerizing at least one recycled methyl methacrylate comprising from 500 ppm to 30.000 ppm by weight of methyl isobutyrate.
A process for producing a waterborne polymer composition, comprising the steps of:
- providing a polymer comprising methyl methacrylate monomer unit;
- recycling said polymer in a recycling process to obtain recycled methyl methacrylate, comprising from 500 ppm to 30.000 ppm by weight of methyl isobutyrate;
- and
- polymerizing said at least one recycled methyl methacrylate obtained in said recycling process;
- wherein the recycling process does not comprise a purification step.
