POLYMER, PROCESS AND COMPOSITION

摘要

There is described a polymer blend of a first and second polymer comprising: a) a first polymer of: vinyl (co)polymer; alkyd; urethane acrylic copolymer; polyurethane and/or polyester; b) a second copolymer from: b1) optionally at least 10 wt-% of one or derivatives of itaconic acid and/or isomers thereof; b2) up to 20 wt-% of one or more acid functional (or potentially acid functional) monomer(s) and b3) vinyl monomer(s) where wt % of each monomer (b1 to b3) is based on total (b) and where at least one of the first and second polymer is obtained from an itacon-functional monomer such as itaconic acid and/or its derivatives.

1. A mixture comprising:
a) a first polymer selected from one or more from the group consisting of: a vinyl (co)polymer; an alkyd polymer; a urethane acrylic copolymer; a polyurethane; a polyester, combinations and/or mixtures thereof; b) a second copolymer obtained and/or obtainable from a second monomer composition comprising:
b1) optionally at least 10 wt-% of one or more monomer(s) selected from derivatives of itaconic acid and/or isomers thereof;b2) up to 20 wt-% of one or more acid functional (or potentially acid functional) monomer(s)b3) vinyl monomer(s) where the percentages given for each monomer (b1 to b3) in the second monomer composition is calculated based on the total amount of monomer (b1 to b3) being 100%; where at least one of the first and second polymer comprise a polymer obtained and/or obtainable from an itacon-functional monomer.
