The invention relates to compositions comprising at least one polymer and at least one plasticizer, in which compositions the polymer is semi-crystalline and exhibits a processing temperature equal to or greater than 220° C., preferably 250° C., and the plasticizer is an aromatic benzenesulphonamide represented by the general formula (I)

The aromatic benzenesulphonamides have little volatility and exhibit good thermal stability, which makes it possible to effectively plasticize polyamides which are processed at high temperatures, such as polyamides-6, -6,6, -4,6, -6,9, -6,10, -6,12 and MDX-6 and polyketones, but also polyamides-11 and -12, polyoxymethylene and poly(vinylidene fluoride).
本发明涉及一种包含至少一种聚合物和至少一种增塑剂的组合物,其中聚合物是半结晶的,处理温度等于或大于220℃,优选为250℃,增塑剂是一种芳香基苯磺酰胺,其通式为(I):
其中,R1代表氢原子、C1-C4烷基或C1-C4烷氧基;X代表线性或支链状的C2-C10烷基、环状脂肪族基、芳香族基;Y代表OH基或2个R2代表C1-C4烷基或芳香族基,这些基团可以自身被OH基或C1-C4烷基所取代。
这些芳香基苯磺酰胺的挥发性很小,具有良好的热稳定性,可以有效地增塑高温加工的聚酰胺,如聚酰胺-6、-6,6、-4,6、-6,9、-6,10、-6,12和MDX-6以及聚酮,还可以增塑聚酰胺-11和-12、聚甲醛和聚偏氟乙烯。
