Dear Achintha Sumithraarachchi, cited below is an article in which the in-situ polymerization of styrene is described. The paper is available on RG. Please let me know if you need any further information.

Dear Achintha Sumithraarachchi, I think you should specify the second component in which styrene is to be polymerized. Prof. Frank T. Edelmann gave an exemple. In situ polymerization is used mainly to prepare :

- blends without phase separation problem, and without using a compatiblizer

- interpentrating polymer netwoks IPN

- composites and nanocomposites

- and others

The following links provide some documents. My Regards

Hi;

I fully agree with Abdelkader BOUAZIZ, the question is very broad and it is essential to specify the environment in which the polymerization reaction takes place.

With my best regards

Dear Achintha Sumithraarachchi, attached is an interesting paper. My Regards

Thank you Prof. Frank T. Edelmann for valuble information. Mr. Abdelkader BOUAZIZ I want to polyerize it on a Nanoparticle like SiO2 . Yes true. currently I'm experiencing the problem you mentioned. the phase seperation. And I'm trying to avoid it.

Dera Achintha Sumithraarachchi, please find attached the results of a liuterature search on the topic "In-situ Polymerization of Styrene on silica nanoparticles". I'm sure that some of the cited papers are available on RG.

Dear Achintha Sumithraarachchi, I am sure that the list of papers attached by Prof. Frank is very rich in documentation. Now because the in situ polymerization is known I want to point out two things. First, the SiO2 porosity and specific surface area are crucial for the polymerization success, and second the soaking or immersion of SiO2 in the monomer also is crucial, this time is for the diffusion of St into SiO2 particles. There are also other parameters to consider. Please feel free to ask for any document it is impossible for you to reach. Good Luck

Dear Achintha Sumithraarachchi

You said that you want to polymerize it on a Nanoparticle like SiO2. I can help you with these two articles:

1- In this article, you can find in-situ polymerization for a similar monomer NIPAAm using RAFT polymerization. The growth of polymer brushes from the solid surface of silica provided a promising tool for surface functionalization and modification, through the “grafting from” method.

2- In this article, the growing of PNIPAAm polymer occurred here with BSA protein following the “grafting to” method (see Supp. Info. for the provided methods). Then, in situ generating of poly(o-phenylenediamine) (POPD) nanoparticles inside a robust and flexible protein-based shell was obtained. If you want more details, let me know.
