Patent ID: 8586672

Claim:
A process for increasing the compatibility between at least two polymers, comprising: (a) the selection of at least two immiscible polymers (A) and (B), wherein the polymer (A) is an acrylic polymer and the polymer (B) is a polyamide, at least one of which does not carry an associative group based on a nitrogenous heterocycle, (b) the modification of the polymer (A) and/or of the polymer (B) in order to obtain a blend of polymers (Pi) resulting from the polymers (A) and (B) which each carry associative groups based on a nitrogenous heterocycle, said associative groups being present in an amount sufficient for the polymers (Pi) to be more compatible with one another than the polymers (A) and (B), wherein the blend of (A) and (B) exhibits a single glass transition temperature.
