    摘要: Soft and low-density foam materials, obtained by means of an extrusion expansion (with physical blowing agents) of particular copolymers of ethylene with vinylacetate (and/or with alkyl esters of acrylic or methacrylic acid), are found to be very suitable for the manufacture of expanded articles with little shrinkage after expansion, free from creases on the surface or cracks on the cell walls, and having excellent characteristics, higher compressive strength and so on.

    摘要: Glass having improved hydrolytic and chemical resistance as well as improved water repellency and mechanical characteristics is obtained by reacting the glass surface with an organoborosiloxane polymer, substituted by one or more of alkyl, aryl, alkoxy, acyl radicals, said organoborosiloxane polymer containing no free hydroxy groups in the presence of one or more organic Ti, Zr, Sn, v compounds at a temperature comprised between 200.degree. and 400.degree.C in order to obtain, through a grafting reaction, a superficial layer of modified glass.
