Discrete hollow microparticle with wall of aminoplast, useful e.g. as compounding agent for thermoplasts, has low bulk density and high flexibility

Discrete hollow microparticles (A) having flexible polymer wall enclosing at least one hollow space, where the wall consists of an aminoplast (I) and the ratio of wall thickness:external particle diameter is at least 1:10. An Independent claim is also included for a method for preparing (A). Die vor...
