Abstract: Hydrophobic polyurethane foams which have densities of from 4 to 15 g/liter and in which the number of closed cells is from 2 to 30%, and the number of open cells from 98 to 70%, based on the total number of cells, are obtained from polyisocyanates, polyhydroxy compounds, catalysts and water, with or without lipophilic compounds, the components being reacted in such amounts that the ratio of hydrogen atoms capable of undergoing a Zerewitinoff reaction to NCO groups is from 1.3 to 10:1. The foams are suitable for the absorption of oil and/or by hydrophobic solvents, which may or may not contain halogen, from water.

Abstract: The sandwich is heated to a point above the m. pt. of the cladding and then pressed together while cooling. The cladding is selected from polyethylene, polypropylene, polystyrene or copolymers of styrene with acrylonitrile or maleic acid anhydride or methyl methacrylate, PVC, PVdC, polyamide, polycarbonate, polymethyl methacrylate reinforced with glass fibres, asbestos, carbon fibres and natural and/or synthetic fibres. The foam core is of polyurethane, urea - formaldehyde resin or phenol - formaldehyde resin. Provides a single - stage process for developing a sandwich laminate for boat or vehicle shells, giving a curved moulding, without adhesives.

Abstract: Method comprises polymerising cyclic formals with cpds contg. double bonds (I) in presence of electrophilic catalysts. Pref. (I) are dialkenylformals. Up to 50 wt.% based on total monomer mixt. of some other, cationically polymerisable cpd(s) may be present. Diallylformal is a suitable (I). Prods. are used as plasticisers (mol. wt. 300-10000), is mfr. of air-drying unsatd. polyesters etc.
