| Poly-p-vinylphenol (MARUKA LYNCUR) |
"MARUKA LYNCUR" is a homo-polymer of para-vinyl phenol. It has a higher molecular
weight than a condensed type phenol resin with a similar structure, in addition,
excels in reactivity and stability, too.
Since its structure is clearly identifiable, "MARUKA LYNCUR" permits you to predict
its reaction and to design its molecular weight, and it may be used to synthesize
various useful derivatives.
"MARUKA LYNCUR M" is available in four groups by molecular weight, so that you
can select a molecular weight according to its application.
"MARUKA LYNCUR" PHM-C is a light-colored polymer obtained by hydrogenating "MARUKA
LYNCUR M". With bromie added, moreover, it has a unique characteristic as reactive
polymer that has incombustibility. |
