Reserch & Development

Maruzen Petroleum Chemical Co. promotes the "development of the basic techniques necessary for the next generation," as represented by the "development of new products that are so unique that they are undreamt of by any other rival companies." For example, these would include: its original products, obtained by conferring additional values to distillation products generated during the synthesis of ethylene; resist materials that meet the needs of society; "highly functional new materials," such as electronic and optical materials; catalysts for olefin polymerization; and the cultivation of a technique for the promotion of highly difficult oxidation. At the same time, from a viewpoint far exceeding that of one private chemical company, Maruzen Petroleum Chemical Co. tries, as one of its main themes, to "develop novel products" that will contribute to the healthy development of our society—including its environmental aspects. Maruzen Petroleum Chemical Co. aims at leading the world in the field of petroleum chemistry techniques and in the development and application of petroleum-based products. This is done by keeping the environment healthy and orderly and by proposing new strategies for a better society where individual members can develop their own potential creativity and sensitivity at their full measure.

An Introduction to Our Newly Developed Products

UV-curing imprint resins

Fine processing based on nano-imprinting is now under study for practical application as an alternative means for the current process of photolithography. The test product developed by us is designed to be highly resistant to dry etching, and thus, it will be profitable when it is used as an etching mask during the processing of the substrates of semiconductors.

Acetylene derivatives

Acetylene obtained as a distillate during the production of ethylene in our plant was extracted and purified. We then employed the acetylene thus obtained as a starting material, converted it, using our unique technique, into vinyl ether, and then succeeded in the commercialization of the latter. Furthermore, aiming at expanding the line-up of products, we are currently engaged in the development of various kinds of not only vinyl monomers (vinyl ether and N-vinyl compounds) but also of many other types of polymers.

Vinyl ether-based resins produced via living cationic polymerization

We have cultivated the technique necessary for the practice of living cationic polymerization through studies jointly made with researchers from universities, and we have been putting our efforts toward the practical application of the technique. We also implemented test equipment at our research center in June, 2010 and started to provide test samples. The implementation of equipment enables the practical application of the technique, which makes it possible to produce various co-polymers, including diblock polymers, ABA triblock polymers, and star polymers, etc., as well as to finely modify the molecular structure of the polymers according to predetermined designs. Currently, making the most of the technique, we are pursuing the development of highly sensitive resins that may vary their shape or properties in accordance with their response to the change of temperature, light, pH, or the like.

Paravinyl phenol resin (PVP)

We have succeeded, for the first time in the world, in the commercialization of PVP resins of industry-grade quality (trade name: Marukalyncur). In addition, we are a top-class supplier in the world of resists useful for the excimer laser-based fabrication of semiconductors. On the basis of such results and on accumulated knowledge, we are developing technical know-how and investing our resources to better meet the quality needs of customers. Making the most of such know-how, we are currently engaged in the design and development of homo-polymers and co-polymers that will better meet the wide-ranging needs of customers.

Bisallylnadiimide (BANI)

BANI (or, a thermosetting polyimide) is highly heat resistant and highly miscible to a variety of solvents and resins. Thus, it is expected that BANI will be profitably applied in various industries. BANI was originally developed by Ciba-Geigy, and we purchased from them the right to further commercialize BANI. Currently, we are the only supplier of BANI in the world, and we distribute it to many customers all over.
