Osaka Organic Chemical Industry LTD STA

Osaka Organic Chemical Industry LTD STA has a very long alkyl chain moiety. Its homopolymers are called Side Chain Crystallization polymers and have not only a Tg but also a melting point (Tm), even though usual acrylic polymers do not have a Tm. The product properties are achieved by its long alkyl chain, comb-like amorphous/semi-crystal phase transition. STA is highly purified, so it can be used for emulsion polymerization due to the absence of alcohol.
