Typesetting: Camera-ready by authors SPIN:I0127464 52/3020-5432 1 0 -Printed on acid -free paper Progress in Pacific Polymer Science 3 The Pacific Polymer Federation (PPF) is an Association of societies in the Pacific region, which have at least part of their activities devoted to polymer science and technology. The Mission of the PPF is to advance and benefit polymer science and technology by encouraging and facilitating interaction between polymer societies in the Pacific region and the exchange of scientific knowledge through visits by polymer scientists and participation in polymer conferences. The PPF was founded in October 1987 by the Division of Polymer Chemistry of the American Chemical Society, the Society of Polymer Science, Japan and the Polymer Division of the Royal Australian Chemical Institute. There are now 14 member societies of the PPF, comprising, in addition to the founding societies: The Society of Polymer Science of Korea (1988), the Macromolecular Science and Engineering Division of the Chemical Institute of Canada (1988), the Polymer and Industrial Section of the Malaysian Institute of Chemistry (1988), the Polymer Division of the Chinese Chemical Society of the People's Republic of China (1989), the Polymer Group of the New Zealand Institute of Chemistry (1989), the Division of High Polymer Physics of the American Physical Society (1990), the Plastics and Rubber Institute of Singapore (1990), the Polymer Society, Taipei (1993), the Division of Polymers and Organic Materials of the Mexican Academy of Materials Sciences (1993), the Division of Polymer Science of the Chemical Society of Vietnam (1993) and the Indonesian Polymer Association (1993). An application for membership is pending from the Polymer Society of Thailand. The policies for the operation and development of the PPF are determined by the Council, which meets once per year. The current Officers of the PPF are: President: Joe Salamone (USA), Vice-President: Chung Yup Kim (Korea), Deputy Vice-President: Renyuan Qian (China), Secretary-Treasurer: Jim McGrath (USA). A PPF Newsletter is published annually. PACIFIC pOLYMER CONFERENCES The main activity of the PPF is to hold a Pacific Polymer Conference every two years, which is organized by the host member society. The 1st Pacific Polymer Conference was held on 12-16 December 1989 in Maui (Hawaii, USA) and the 2nd Pacific Polymer Conference was held at Lake Biwa, otsu, near Kyoto (Japan) on 26-29 November 1991. The 3rd Pacific Polymer Conference, PPC-3, was held on 13-17 December 1993 at the Gold Coast, Queensland, Australia and organized by the Polymer Division of the Royal Australian Chemical Institute. There were 528 participants, including 117 students) from 23 countries, with the highest numbers coming from Australia (277), Japan (121), USA (40) and Korea (30). The scientific program comprised 50 Invited Lectures, 250 contributed Oral Presentations and 150 Posters, with up to 9 concurrent sessions. There were also Plenary Forums on "'The Future of Polymer VI Science and Technology in the Pacific Region" and "Polymer Materials and the Environment". The 4th Pacific Polymer Conference will be held in Kauai (Hawaii, USA) in December 1995, the 5th Pacific Polymer Conference in Korea in 1997 and the 6th Pacific Polymer Conference in China in 1999. pROGRESS IN PACIFIC pOLYMER SCIENCE Invited Lectures from each Pacific Polymer Conference have been published by Springer-Verlag as a hard-cover book of about 350 pages with the title: "Progress in Pacific Polymer Science··, and provides a permanent record of the current status of major topics in polymer science. The 3rd Pacific Polymer Conference continues this tradition with this publication of ··Progress in Pacific Polymer Science 3". ACKNOWLEDGEMENTS The 3rd Pacific Polymer Conference was organized by a Committee of 30 Australian polymer scientists, assisted by an International Advisory Committee representing all of the member societies of the PPF and an Honorary Advisory Committee.

In spite of its importance, there are a very few studies because of experimental difficulties. In this study, we have overcome the difficulties and determined precise coexistence curves of polymer blends.[1-4] Taking advantage of the established coexistence curves, we have studies kinetics of early and late stages of phase separation. As to the early stage, time-evolution of concentration fluctuations in the metastable region has been studied using time-resolved synchrotron small-angle x-ray scattering.[5] For the late stage, the crossover from co-continuous to droplet structure has been investigated, which is primarily governed by the fractional phase volume.[6] Furthermore, using the information obtained here, the morphological structure induced by two-step temperature jump has also been investigated.[7-9] Through these studies, we will demonstrate importance of the coexistence curve in studying phase-separation kinetics. EXPERIMENTAL Materials and Samples Polystyrenes(PS) were commercial ones with narrow molecular weight distri butions. Poly(2-chlorostyrene)s(p2CIS) were radically polymerized and fraction ated to be of narrow molecular-weight distribution. Characteristics of PS and P2CIS used and their sample codes are listed in Table 1. Di-n-butyl phthalate (DBP) , which is thermodynamically good for both of PS and P2CIS, was added to the blends for adjusting the phase boundary and the phase separation to appropriate range of temperature and rate, respectively. Blend systems used and their codes are shown in Table 2, and the sample code Y-PSXX, specifying the blend system Y with PS volume composition XX % in the total polymers, will be used. K.P.
