A granulated or pelletized composition of propylene homo and copolymers onto which are grafted grafting units of vinylpolybutadiene and further grafting units selected from polyalkenylenes, EPM and EPDM polymers, and mixtures thereof. The composition has a Shore D hardness value equal to or less than 35 and a fogging value equal to or greater than 90%. The composition is suitable for injection molding. A method of producing the granulated or pelletized composition comprising forming the composition by mixing the propylene homo and copolymers, vinylpolybutadiene grafting units and further grafting units with peroxide radical initiators, extruding the composition under heat and granulating the extruded polymer composite. An interior car door panel or interior car trim element having an outer skin made of granulated or pelletized forms of the composition.

Granulated or pelletized compositions of grafting units

Panels and elements for vehicle interiors are obtained by co-extrusion or co-lamination of a layer (,) of themoplastic support material containing a reinforcement filler with a layer (,) of thermoplastic covering material containing an amorphous thermoplastic and by thermoforming the resulting sheets in a press.

Process and a aparatus for production of multilayer trim elements for vehicles

Polymers and copolymers of propylene are modified by grafting with polyalkenylenes having a trans double bond content of higher than 30%. The preparation is carried out via thermic treatment of the propylene (co)polymer with said polyalkenylene at a temperature comprised between 200.degree. and 350.degree. C. an the presence of a free radical initiator other than peroxide.

Propylene polymers grafted with polyalkenylenes and process for their

A process for producing bodies of polymeric material having an outer shell and a core of foamed material is disclosed. The process includes the steps of: providing a mold having a pair of separable half-molds arranged facing each other; extruding a tubular thermoplastic parison between the half-molds; closing the half-molds around the parison, thereby defining a hollow space between the parison and walls of the mold; injecting into the inside of the parison a thermoplastic polymeric material admixed with a physical blowing agent, the parison expanding into contact with the walls of the mold, and conforming to the shape of the mold; and removing the article form the mold.

Crystalline propylene (co)polymers modified by grafting with a vinylpolybutadiene having 1,2-structure content of at least 10%. Said (co)polymers are reacted with a liquid vinylpolybutadiene in the presence of a non-peroxidic radical initiator at a temperature in the range 200.degree. to 350.degree. C., the liquid vinylpolybutadiene having a 1.2-structure content of at least 10% and being generally used in amounts within the range 0,5 to 20% by weight.

Crystalline propylene (co)polymers modified by grafting with a vinylpolybutadiene having 1,2-structure content of at least l0%. The (co)polymers are reacted with a liquid vinylpolybutadiene in the presence of a non-peroxidic radical initiator at a temperature in the range 200.degree. to 350.degree. C., the liquid vinylpolybutadiene having a 1,2-structure content of at least 10% and being generally used in amounts within the range 0.5 to 20% by weight.

an apparatus for producing bodies of polymeric material having an outer shell and a core of foamed material is disclosed. The apparatus includes an extruder and accumulation chamber for extruding a tubular element, i.e., a parison, and a second extruder and accumulation chamber for injecting a foamable polymeric material for forming the core of the body inside the parison. The injection occurs inside the walls of a mold, which causes the tubular parison to undergo swelling due to the expansion of the foamable material until the parison conforms to the shape of the mold.

Process for preparing thermoinsulating and/or structural formed articles

A process for preparing structural, heat-insulating shaped bodies which does not necessarily require the use of a foamed heat-insulating material obtained by the use of blowing agents belonging to the class of chlorofluorocarbons. The process includes inserting a heat-insulating pre-molded core inside a tubular element made from an extruded thermoplastic polymer; placing the extruded tubular element containing the pre-molded core into a blow-molding mold; and molding the tubular element into a shell by blow-molding. By subsequent mold closure, the shell adheres to the pre-molded core. An alternative process is disclosed for adhering the tubular element and pre-formed core by closing the mold and drawing a vacuum within the tubular element.

Process for preparing structural, heat-insulating shaped bodies, and

This application discloses a grid for electric household appliances made from a thermoplastic polymer, comprising a peripheral edge whose perimeter is of substantially quadrangular shape, and a plurality of rods inserted inside said edge, parallel to one of the sides of the perimeter, and united to said edge without discontinuities.
