Abstract: The invention relates to agglomerates of flame-retardants, in particular melamine cyanurate, containing aggregates with an average size of between 0.1 and 50? bonded to each other with the aid of an auxiliary material. This auxiliary material is present in a concentration of between 0.1 and 10 wt. %, relative to the total agglomerates weight, and has a softening point higher than 40° C. The invention further relates to a method for producing said agglomerates, the use of the agglomerates in the preparation of polymer compositions, and polymer compositions containing melamine cyanurate.

Abstract: The invention relates to a compound of formula I: where: X is equal to NR5; R4 is equal to a C1-C12 alkyl group, aryl group, aralkyl group or cycloalkyl group. R1, R2, R3, R5 are equal to an H, alkyl, cycloalkyl, aryl of heterocyclic group; where R1, R2, and R5 or R1, R2, and R3 may together form a heterocyclic group. The invention also relates to a method for the preparation of this compound by reaction of an amino compound with an alkanol hemiacetal. The invention also relates to amino-aldehyde resins containing this compound and the application of these resins in adhesive compositions, laminates, shaped articles and transparent coatings.
