Abstract: Finely divided expansible styrene polymer particles, for the prodn. of foram mouldings, contain 0.0001-0.2 phr of a nucleating agent (I) in non-homogeneous distribution, (I) being situated only in a thin band at the surface of the particles and virtually absent in the interior. Mouldings obtd. from the particles can be demoulded after a short dwell-time in the mould, have very low thermal conductivity (due to the coarse internal pore structure), have good dimensional stability (i.e. no lateral depression) and have homogeneous density.

Abstract: Adhesive film (I) is based on a thermoplastic polymer (II) and contains 1-50 wt.% of a liq. (III) which swells but does not dissolve (II) and lowers its Tg by more than 20 deg.C. (II) is a polyether-sulphone, polyamide, polycarbonate, polyether-e or thermoplastic polyurethane; (I) is 20-2000 microns thick and contains reinforcing fibres and/or metal ply. USE/ADVANTAGE - (I) is useful for bonding moulded parts of thermoplastics. Bonding such moulded parts comprises placing (I) (based on the same polymer as the parts) between the parts and pressing the assembly together at a temp. below the Tg of the pure polymer but above the Tg of the swollen polymer; pref. the pressure applied is higher than the vapour pressure of (III) at the test temp.. Suitable (III) are, e.g. MEK, acetone, CH2Cl2 (for polyether-sulphone); water/ethanol or water/ethanol/ketone (for polyamide 6, 66, 6/66 etc.); DMF and/or ketone (for thermoplastic PU); ketone and/or CH2Cl2 (for polycarbonate); THF and/or CH2Cl2 (for polyether-imide).

Abstract: The invention relates to a continuous process for the production of elastic foams based on melamine resins, in which a mixture of an aqueous solution of a melamine-formaldehyde precondensate, an emulsifier, a curing agent and a volatile blowing agent is foamed and cured, and the resulting foam is dried to a water content of less than 10% by weight and then conditioned with the aid of through-flowing hot gases. According to the invention, the drying is carried out by ultrahigh-frequency irradiation.

Abstract: Particulate self-extinguishing thermoplastic molding compositions based on styrene polymers containing volatile blowing agents are surface-coated with an organic bromine compound and, to stabilize the bromine compound against photodegradation, a N-hydroxyphenylbenzotriazole or a hydroxybenzophenone. The molding compositions may be used for the manufacture of foams by expanding the blowing agents at elevated temperatures.
