@ There are provided a wide range of polyurethane products, e.g., cellular, dense elastomer, and integral skin mlcrocellular products, obtained by the reaction of (a) a polylsocyanate compound, (b) a polyol, (c) optionally a chain extender and/or blowing agent with/without other known additives, (d) in the presence of a nonhydroxyl flow modifier characterized by carbon and hydrogen atoms, at least one and, generally, a plurality of oxyalkylene groups, O I and at least one urethane, -NHCO-, group. Several of the polyurethane products exhibit unique properties, e.g., foamed articles with capability to conduct static electricity, soft elastomers characterized by improved coefficient or friction, etc. Several classes of the flow modifiers are novel per se. The polyurethane products can be synthesized via the one shot or prepolymer process. Multipackage systems, In particular, two and three component systems are useful In molding operations, e.g., manufacture of shoe soles.
提供了多种聚氨酯产品,如:蜂窝状、致密弹性体和整体表皮的多孔产品、(a) 一种多异氰酸酯化合物;(b) 一种多元醇;(c) 一种可选的扩链剂和/或发泡剂(含/不含其他已知添加剂);(d) 一种非羟基流动改性剂,其特征在于该流动改性剂含有碳原子和氢原子、至少一个(一般为多个)氧烷基 O I 和至少一个氨基甲酸酯基 -NHCO-。有几种聚氨酯产品具有独特的性能,例如,具有静电传导能力的发泡制品、具有改善摩擦系数特点的软弹性体等。有几类流动改性剂本身就很新颖。聚氨酯产品可通过一次成型或预聚工艺合成。多组分系统,特别是双组分和三组分系统在模塑操作中非常有用,例如鞋底的制造。
