摘要： An improved method for the suspension polymerization is proposed which gives a PVC resin product having an increased plasticizer absorptivity and greatly decreased content of fish eyes. The invention can be achieved by additionally adding a limited volume of water into the polymerization mixture under proceeding of the polymerization reaction within a specified period of 30 to 70% monomer conversion and at such a controlled rate as not to unduly decrease the pressure inside of the reactor. The improvements are particularly remarkable when the dispersing agent added to the polymerization mixture is a ternary combination of (A) a water-soluble partially saponified polyvinyl alcohol of a high degree of polymerization and a high degree of saponification, (B) a hydroxypropyl methyl cellulose having specified degrees of substitution with methoxy and hydroxypropoxy groups and specified viscosity characteristics and (C) a monomer-soluble partially saponified polyvinyl alcohol of a low degree of polymerization and a low degree of saponification, each in a specified amount.

摘要： The invention provides a high molecular weight silicone compound comprising recurring units of formula (1) and having a weight average molecular weight of 1,000-50,000. Some or all of the hydrogen atoms of carboxyl groups or carboxyl and hydroxyl groups in the silicone compound may be replaced by acid labile groups. Z is a di- to hexavalent, non-aromatic, monocyclic or polycyclic hydrocarbon or bridged cyclic hydrocarbon group; Z is a di- to hexavalent, normal or branched hydrocarbon group or non-aromatic, monocyclic or polycyclic hydrocarbon or bridged cyclic hydrocarbon group; x, y and z are integers of 1-5 corresponding to the valence of Z and Z′; R1 is —OCHR—R′—OH or —NHCHR—R′—OH; R2 is alkyl or alkenyl or a monovalent, non-aromatic, polycyclic hydrocarbon or bridged cyclic hydrocarbon group; p1, p2, p3 and p4 are 0 or positive numbers. A resist composition comprising the high molecular weight silicone compound as a base resin is sensitive to actinic radiation and has a high sensitivity and resolution so that it is suitable for microfabrication with electron beams or deep UV. Since the composition has low absorption at the exposure wavelength of an ArF or KrF excimer laser, a finely defined pattern having walls perpendicular to the substrate can be readily formed.
