Abstract: In grafting ethylenically unsatd. carboxylic acids, anhydrides and/or derivs. onto ethylene (co)polymers with density below 0.930 g/cc, in an extruder or mixer at 1-500 bar, in absence of a radical catalyst, 0.01-0.5 wt.% of the monomer to be grafted is mixed with the ethylene polymer melted at at least 140 deg.C, and grafting is carried out at 210-300 deg.C.

Abstract: In the prodn. of graft copolymers (I) by grafting ethylenically unsatd. carboxylic acids and/or carboxylic anhydrides on polyolefin mixts (II), the novelty is that (II) consists of 51-95 (wt.)% (co)polyethylene (III) and 5-49% ethylene-propylene block copolymer (IV) other than (III). Pref. (IV) contains over 35% elastomer (determined as xylene extract at 80 deg. C). (II) contains 5-20, pref. 8-12 pts. (IV). (III) has a density of min. 0.930 g/cc.

Abstract: The process for the preparation of crosslinkable copolymers of propylene at elevated temperature by reacting propylene with from 0.05 to 2% by weight of alpha ,ss-ethylenically unsaturated carboxylic acids and/or esters thereof, or anhydrides thereof, characterised in that a multifunctional amine is added, as crosslinking agent, to the copolymer, the temperature and residence time are set so that an as yet uncrosslinked, but crosslinkable mixture is formed, and this mixture is rapidly cooled.

Abstract: Prodn. of internal parts for refrigerators involves placing an inner container of high impact polystyrene (PS) in an outer container of sheet metal and filling the cavity with rigid polyurethane (PUR) foam contg. a fluorochlorohydrocarbon (I) by foaming in situ. The novel features are that (a) (I) is 1,1,1-trifluoro-2,2- dichloroethane (R 123) and/or 1,1-dichlorofluoroethane (R 141b) and (b) the PS has a cell particle morphology with an average particle dia. of 2.5-3.5 microns, a soft phase fraction of 48-48 wt.%, a viscosity of 65-75 ml/g. for the hard phase and a Vicat B temp. of 82-94 deg C.
