Thermoplastic molding compounds

The invention relates to thermoplastic moulding materials containing A) between 10 and 99 % by weight of at least one thermoplastic polymer, B) between 1 and 50 % by weight of a mixture consisting of b1) at least one phosphorous compound and b2) at least one stabiliser compound of the general formulas (I) to (IV). In formula (I), R and R represent, independently of one another, a hydrogen radical, a C1 to C10 alkyl radical, a C6 to C12 aryl radical, a C7 to C13 aralkyl radical, or a C7 to C13 alkylaryl radical, a, b independently of one another, have the values 1 to 5, c, d independently of one another, have the values 0 to 10. In formula (II), R represents a hydrogen radical, a C1 to C10 alkyl radical, a C6 to C12 aryl radical, a C7 to C13 aralkyl radical, a C7 to C13 alkylaryl radical, e has the value 1 to 4, f has the value 1 to 100. In formula (III), R and R independently of one another, represent NCO or NHCOOR', whereby R' represents an alkyl polyetherglycol or an alcohol containing between 1 and 20 C-atoms, R , R , R , R , R , R , R , R independently of one another, represent a hydrogen radical, a C1 to C10 alkyl radical, a C6 to C12 aryl radical, a C7 to C13 aralkyl radical, a C7 to C13 alkylaryl radical, g indicates 0 to 5, h indicates 1 to 100. In formula (IV) R , R , R independently of one another, represent a hydrogen radical or a radical (a), whereby R represents a hydrogen radical, a C1 to C10 alkyl radical, a C6 to C12 aryl radical, a C7 to C13 aralkyl radical, a C7 to C13 alkylaryl radical, or (CH2)1-N=C=O, whereby 1 indicates 1 to 20, i indicates 2 to 8, j indicates 1 to i-k, k indicates 0 to i-j, whereby j + k
