The invention concerns a method for preparing stable (co)polymer dispersions in a polyol by polymerising in situ a monomer or a mixture of ethylenically unsaturated monomers, in the presence of one or several azocarboxylic acid ester(s).

Method for preparing stable (co) polymers dispersions in a polyol

Multilayered article including a vulcanized elastomer associated directly with a thermoplastic

The present invention relates to a process for forming composite shaped articles used for athletic shoe soles, tubes, pipes, transmission belts and conveyor belts, comprising a vulcanized elastomer directly or autogenously bonded, that is, essentially in the absence of adhesive, to a thermoplastic elastomer comprising recurring polyamide-6 and polyether structural units, such as thermoplastic polyetheresteramide elastomers, are provided. The article is prepared by a process comprising placing a thermoplastic elastomer component into a vulcanization mold, overmolding onto at least a portion of the surface area of one face surface of the thermoplastic elastomer component with a vulcanizable elastomer component, and vulcanizing the vulcanizable elastomer component at a temperature below the melting point of the thermoplastic elastomer component but over a wide temperature range, which can be about 40&deg; C. or higher.

Composite shaped articles comprising vulcanized elastomers autogenously bonded to polyamide/polyether thermoplastic elastomers

This composition, which is useful as a binder in the preparation of synthetic resin concretes or mortars, bonding primers or finishing coats, comprises (A) a system of monomers comprising: (a1) 50-90 parts of a dicyclopentenyloxyalkyl eater:

Composite including a rubber/thermoplastic blend adherent by itself to a thermoplastic material; the blend is in the form of a thermoplastic matrix containing rubber nodules functionalized and vulcanized during the mixing with the thermoplastic. Composite articles obtained by overmolding the vulcanized rubber/thermoplastic blend onto the thermoplastic.

Blends of thermoplastic and rubber which are adherent to thermoplastics

Composite including a rubber/thermoplastic blend adherent by itself to a thermoplastic material; the blend is in the form of a thermoplastic matrix containing rubber nodules functionalized and vulcanized during the mixing with the thermoplastic. Composite articles obtained by overmoulding the vulcanized rubber/thermoplastic blend onto the thermoplastic.
