Abstract: Preparation of ethylene polymers (A) by a high pressure process involves dissolving radical initiator(s) in ketone(s) (I); compressing; dosing the mixture to the polymerization reactor in one or more portions; and carrying out polymerization. Preparation of ethylene polymers (A) by a high pressure process involves: (1) dissolving radical initiator(s) in ketone(s) of formula R 1-CO-R 2(I); (2) compressing; (3) dosing the mixture to the polymerization reactor in one or more portions; and (4) carrying out polymerization at 140-350[deg]C and 400-4500 bars. R 1, R 21-6C alkyl or 3-12C cycloalkyl; or are linked to complete a 4-13 membered ring.

Abstract: A 5-300mm thick plastic layer (2) is sandwiched between two metal layers(1,4), 1-20mm thick. Surfaces of the metal layers facing the plastic have raised areas(3,5) with a height of 0.1-15mm to increase grip between the layers. Raised areas(3,5), preferably 0.1-2mm in height, are produced in the metal layers(1,4) and the metal layers are fixed in position. Space between them is then filled with an initially liquid material to produce a plastic layer(2). The space between the metal layers is sealed to contain the fluid plastic before introduction of the latter. Independent claims are included for a process for manufacturing the composite product in which raised areas or projections are produced by filing, rolling, pressing or grinding.
