preparation example Construction

[0075] In order to improve the preparation of rubber compositions, it is desirable that the metal halide is further complexed with a complexing agent such as water, alcohol and ether. Such complexed metal halides have improved solubility and dispersibility in rubber compositions. A preferred example is tin dichloride dihydrate. The preferred amount of metal halide as activator package iii) is from 0.25 to 5.0 parts, preferably 0.5 to 2 parts, per 100 parts of elastomeric polymer i).

[0076] In another preferred embodiment of the invention, the activator package iii) comprises a halogenated organic compound.

[0077] Suitable halogenated organic compounds are those from which the hydrogen halide is split off in the presence of the metal compound.

[0078] Halogenated organic compounds include, for example, polymers or copolymers of vinyl chloride and / or vinylidene chloride and other polymerizable compounds, halogen-containing plastics, such as polychloroprene; halogenated, s...

[0112] general program

[0113] The zeolite / polymer masterbatch compositions of the examples were prepared using an internal mixer (Shaw K1 Mark IV Intermix) having a capacity of 3 liters with intermeshing rotating blades and an onset temperature of 25°C. Zeolite 5A was weighed and the zeolite / polymer masterbatch mixed for no more than 10 minutes thereafter. The elastomeric polymer is first introduced into the mixer and allowed to comminute for a period of 30 seconds using a rotor speed of 45 rpm before adding the zeolite 5A powder (which is an aluminosilicate powder with a particle size below 50 μm), at a rate of less than A moisture content of 1.5 wt% was supplied. Mixing was carried out maintaining the same rotational speed until a batch temperature of 140°C was achieved for the 40wt% masterbatch, taking 8 minutes of total mixing time, and 155°C for the 80wt% masterbatch, taking a total mixing time of 13 minutes, at which point the batches were Once removed from the inter...

Abstract

Polymer composition containing a) a polymer, b) a zeolite, whereby the total amount of the components a) and b) in the composition is higher than 90 wt%, in particular higher than 94 wt%, more preferred higher than 98 wt% and the total amount of water determined by TGA in the temperature range of 25 to 380 DEG C with a rate of 5 DEG C / min is lower than 15 wt%, based on the amount of residuals obtained after the TGA measurement has been continued to 550 DEG C.

Description

technical field [0001] The present invention relates to a polymer composition, a method for its manufacture and its use for curing a resin comprising a curable polymer composition. Background technique [0002] Zeolites as known from EP2441798 and EP2650327 are used to improve the curing rate and the curing state of resinous crosslinkers in curable rubber compositions. To achieve these desired benefits, zeolites are used in activated form, primarily by drying to remove moisture or other volatiles that can deactivate the zeolites. This processing requires certain conditions and equipment that may not be available at all to customers simply wanting to apply this technology. It was therefore an object of the present invention to find out how to provide zeolites for this curing reaction without losing too much of their activity to give reproducibly good curing results. Contents of the invention [0003] This object is achieved by providing a polymer composition comprising: ...
