    • This invention concerns cationic laminar compounds which are especially suited for stabilizing halogen-containing plastics against thermal or photochemical decomposition. These cationic laminar compounds can be made by using laminar compounds of the general formula (I) [EeZzDdVv(OH )x](A )a . q H2O in which: E is a monovalent cation from the alkali metal group, e is a number in the range of 0 to 2, Z is a bivalent metal cation, z is a number in the range of 0 to 6, D is a trivalent metal cation, d is a number in the area of 0 to 3, V is a tetravalent metal cation, v is a number in the range of 0 to 1, (A ) is an acid anion of charge n-, where n is a whole number from 1 to 3 and q is a number in the range from 1 to 10, with the proviso that x>a and e + 2z + 3d + 4v = x + na, which one subjects to an alkali induced maturation in an aqueous medium, whereby the molar alkali hydroxyde content of the aqueous medium is set in the range of 1 to 6, the crystallization temperature in the range of 60 to 100 DEG C and the crystallization period in the range of 2,5 to 50 hours.
    • (A )一 - 通过使对应于通式(I)[(<> OH)X EeZzDdVv]层的化合物而得到的阳离子性层状化合物。 q H 2 O,其中E是选自碱金属的一价阳离子,例如是一个数字范围从0到2,Z是一个二价金属阳离子,z为0至6范围内的数,D是三价金属阳离子, d是一个数字范围从0到3,V是四价金属阳离子,v是一些范围从0到1中,(a )n-表示与电荷的酸阴离子,n是1-3的整数 和q是一个数字范围从1至10,条件是x> a和e + 2Z + 3D + 4V = X + NA,在碱诱导的成熟的水性介质中,进行其中的一个的内容 碱金属氢氧化物的在1-至6-摩尔水性介质中,结晶化温度在60〜100℃的范围内,在2.5至50小时组的范围内的结晶时间,特别适用于稳定化抵抗热的含卤塑料 或光化学降解。
