We consider some classes of infinite-dimensional Banach spaces with integrable derivatives. A compactness lemma for nonreflexive spaces is obtained. However some main topological properties for the given spaces are obtained. This work is continuation of [1]. Theorem 1.);(*0 HSCW ⊂ with continuous embedding.
