Natural Latex and Polyethylene mixing
« on: September 27, 2018, 04:32:09 PM »
I was wondering if chemical experts could explain a method to me for dissolving polyethylene powders in natural Latex.
I have tried  to mix them but latex has been coagulated immediately.
How can I prevent latex from coagulation in this condition?
Thank you.

I assume you're using heat?

Given that natural latex is an aqueous dispersion of polymer particles, it's no surprise it doesn't readily mix with polyethylene. You may need some kind of compatibilizer.

Let's make sure we are using the right terminology here. Polyethylene is not soluble in very many things. is it mixing or true solulibization

Dear Corribus,

Thank you for your prompt reply. I have not  used heat for my experiment.I would appreciate it if you could tell me that
it is necessary to use heat in this case or not.
Which kind of compatibilizers is much more appropriate in this regard?
How can I overcome with latex agglutination during high rapid mixture?

Yours sincerely,
M.Haddadi

Dear wildfyre,
Thank you for your consideration.
Actually,I would like to mix both of them as homogeneously as I can.
How can I prevent the agglutination of latex  with UHMWPE during mixing?
I have done it under vacuum conditions.

Yours sincerely,
M. Haddadi

It might be helpful to have a little more information about what you are trying to do. Latex is largely water. Polyethylene doesn't like water. So just putting them in a pot and stirring isn't going to do much. You will need to heat the mixture up, probably past the melting point of polyethylene (110-140 C depending on what kind you have), boil off most of the water, and hope the polymer phase of the latex is sufficiently compatible with the PE to mix in the melt, and stay mixed when you cool it back down. It's possible you still may get a phase separated mixture when you cool it down.

When you try to mix two homopolymers, typically they will phase seperate over time. This usually ruins the material properties.

What you are asking for is not trivial, and frankly not suited for asking broadly on the internet. I would try to hire a consultant chemist in the field. I'm a formally trained PhD polymer chemist and I do not know the answer to your question. It requires specific expertise.

Corribus' answer to just heat it all up and hope it stays mixed is the best advice I could give if you don't have any other resources.
