example C1、2-4 and C5

[0263] The foams of Examples C1, 2-4 and C5 were prepared according to the general procedure as described above. First, by combining the polymer and TiO 2 (2 wt.% relative to the total weight of composition (C)) was fed into the first barrel section of a 25 mm Berstorff co-rotating intermeshing twin-screw extruder at a rate of 22 lb / hr (10 kg / hr) To produce the foaming compound. The barrel temperature settings for barrel sections 2 to 8 were set at the following temperatures, respectively: 260°C, 290°C, 300°C, 300°C, 320°C, 340°C, and 340°C and no heat was applied to the extruder for The material throat is located on barrel section 1. The die temperature setting was 330°C. The extruder screw speed used was 130-140 RPM. The foaming method used was the same one described above under the heading "General procedure for the preparation of the foam (P)". In this foaming method, isopropyl alcohol was used as a foaming agent and its concentration was set at 8 wt%. Foam was extru...

example C7、8-10

[0266] Examples C7, 8-10 and C11

[0267] The foams of Examples C7, 8-10 and C11 were prepared according to the general procedure as described above. First, by combining the polymer, Vapor talc (for quantities see Table 2 below) and A physical mixture of 1010 (0.125 wt.% with respect to the total weight of composition (C)) was gravimetrically fed to a 25 mm Berstorff co-rotating intermeshing twin-screw extruder at a rate of 25 lb / hr (11.4 kg / hr). The foaming compound is prepared in the first barrel section. The barrel temperature setting for barrel sections 2 to 8 was set at 300°C and no heat was applied to barrel section 1 where the feed throat of the extruder was located. The die temperature setting was 340°C. The extruder screw speed used was 200 RPM. The foaming method used was the same one described above under the heading "General procedure for the preparation of the foam (P)". In this foaming method, ethanol was used as a foaming agent and its concentration was ...

Abstract

A foam material having one glass transition temperature (Tg) and made from an immiscible composition having at least two glass transition temperatures (Tg) by an extrusion process wherein said composition (C) comprises at least one polyarylene (P1) polymer, wherein more than 50 % by moles (moles %) of the recurring units of said (P1) polymer are recurring units (R1) consisting of an arylene group, wherein said arylene group is a hydrocarbon divalent group consisting of one core composed of one benzene ring or of a plurality of benzene rings fused together by sharing two or more neighboring ring carbon atoms, said benzene ring being optionally substituted, wherein each of said arylene group is bound to two other arylene groups of neighboring recurring units (R1) through a first C-C bond (E1) and a second C-C bond (E2), wherein at least 20 moles % of recurring units (R1) are kink- forming arylene units (R1-b), the remainder being rigid rod- forming arylene units (R1-a) different from aryleneR1_b units, wherein in said aryleneR1_a units the bond (E1) and the bond (E2) are co-linear and anti- parallel towards each other, said (P1) polymer being present in composition (C) in an amount of below 75 % by weight (wt. %) and above 10 wt. % based on the total wt. % of (P1) polymer and (PPSU) polymer, and (ii) at least one polyphenylsulfone polymer, said (PPSU) polymer being present in composition (C) in an amount of below 90 wt. % and above 25 wt. % of based on the total wt. % of polyarylene (P4) polymer and (PPSU) polymer.

Description

[0001] This application claims priority to U.S. Provisional Application No. 61 / 734019, filed December 6, 2012, and European Application No. 13154975.0, filed February 12, 2013, the entire contents of each of these applications being incorporated for all purposes Incorporated herein by reference. field of invention [0002] The present invention relates to polymeric foams, and in particular, to polyarylene / polyphenylsulfone (PPSU) foams. The invention further relates to methods of making said foams and articles made therefrom. Background of the invention [0003] It is known that there is a growing need for high strength polymeric foams to be used in lightweight applications such as transportation (especially aviation), mobile electronics, construction materials, housewares, food service trays, and medical, among others. The use of said high-strength polymer foams, especially in lightweight structures (like for example in structural sandwich panels) implies key properties su...
