Abstract

Apparatus for treating naturally occurring polymers, such as gums or resins from plants or trees, the apparatus comprising a heated reservoir 1 to contain a quantity of polymer, one or more inlets 15 for the introduction of additives/reactants, mixing means 4, 17, 18, and a pump 12 for transferring polymer from the reservoir 1 to the mixing means 4, 17, 18. The polymers may be converted to a plastics material or used in adhesives, fillers or paints.

Description

23929 1 2
POLYMER CONVERTER
The machine convert" naturally occurring polymers each as resin or gum covered from living trees into polymers that can be used commercially such as plastic", adhesive", fillers, paint", and/or hybrids.
The is gum is heated in a reservoir which feeds a pump from which it paggeg via, a flow control valve into a cylindrical mixer where further constituents and/or catalyst" and/or kinetic energy are added through access port then mixed. The desired polymer then passes out through pelleting digest A preferred embodiment of the invention will now be described with reference to the accompanying drawing" in which.

other constituents for mixing with the naturally occurring polymer and a pump having fluid connections to allow the naturally occurring polymer to be drawn from the reservoir and delivered to the mixing means.
2. Apparatus as claimed in claim 1, where the naturally occurring polymer is a resin obtained from living trees.
3. Apparatus as claimed in the preceding claims, where the naturally occurring polymer is converted into a plastics material.
4. Apparatus as claimed in claim 1 or claim 2, where the naturally occurring polymer is converted into an adhesive.
5. Apparatus as claimed in claim 1 or claim 2, where the naturally occurring polymer is converted into feedstock for fillers.
6. Apparatus as claimed in claim 1 or claim 2, where the naturally occurring polymer is converted into feedstock for paints.
7. Apparatus as claimed in claim 1 or claim 2, where the naturally occurring polymer is converted into a hybrid polymer of any or all of those claimed in claim 3 to claim 5.
