[0096]Materials

[0097]EVS (2.1%) MA (26%) Terpolymer produced by a high pressure tubular reactor in a conventional manner using conventional peroxide initiator, with a max temperature of 285° C., where ethylene monomers were reacted with vinyl trimethoxysilane (VTMS) and methylacrylate (MA) co-monomers amounts so as to yield 2.1 wt % vinyl trimethoxy silane content and 26 wt % MA content in the terpolymer. CTA was used to regulate MFR as well known for a skilled person. The melt flow rate (MFR2@190° C.) according to ISO 1133 (190° C., 2.16 kg) is 20 g / 10 min and a melting point of 85° C.

[0098]Compounding of the Blends

[0099]The different compounds were compounded on a pilot scale extruder (Prism TSE 24TC). The obtained mixture was melt mixed in conditions given in the table below and extruded to a string and pelletized.

Abstract

A polymer composition with a polymer of ethylene with a comonomer with silane group(s) containing units and an additive that is an organic compound with at least one amine moiety that has a gel content less than 10 wt % after 7 days at ambient conditions and a gel content of at least 15 wt % gel content after 14 days at 100° C. The film can be used in a laminate.

Description

FIELD OF INVENTION[0001]This invention relates to a film. The film is made from a polymer composition having a polymer of ethylene (a) with a comonomer with silane group(s) containing units that are hydrolysable and an additive (b), wherein the additive is an organic compound which comprises at least one amine moiety. The film has the characteristic that it has a gel content less than 10 wt % after 7 days at ambient conditions and a gel content of at least 15 wt % gel content after 14 days at 100° C.[0002]The invention also relates to a process for making the film and a laminate with the film.BACKGROUND OF INVENTION[0003]There are many and various laminates. The laminate sought by this invention is a laminate that comprise at least one glass layer and at least one layer made of a polymer. The object of these two layers is good optical properties and good high temperature properties, i.e. that the laminate can be used in warm places. Commonly other layers with further functionality a...
