Further, it can be avoided that a specific viscosity of the copolymer of the alkyl vinyl ether and maleic anhydride is lowered, by means of a method for producing a copolymer of alkyl vinyl ether and maleic anhydride which comprises shielding oxygen in a polymerization, as disclosed in the third aspect of the present invention.

  • Patent number: 6780964
    Abstract: A method for preparing a polyether polyol copolymer includes the step of copolymerizing (1) a cyclic ether represented by the following formula (I): wherein x is an integer ranging from 2 to 10; (2) a diol represented by the following formula (II): HO—(CH2)x—OH  (II) wherein x is the same as that specified above; and (3) other polyols, in the presence of an acid catalyst. The method permits the arbitrary modification of the content of the O(CH2)x units present in the main chain of a polyether polyol copolymer so that the copolymer may have an appropriate crystallinity suitable for use as an elastomer by controlling the ratio of the diol represented by Formula (II) used in the copolymerization and simultaneously permits the change of the molecular weight of the resulting polyether polyol copolymer.

  • Patent number: 6730764
    Abstract: A concrete retarder comprises a polymer (A) having the concrete set retarding ability. The polymer (A) has, as a structural unit, a low glass transition temperature (Tg) component with a Tg of not higher than −5° C., and a surface tension of 45 mN/m or lower. The proportion of the low Tg component having a glass transition temperature (Tg) of not higher than −5° C. is 10% by weight or more relative to the whole polymer (A). The polymer (A) has a functional group which can form a salt with a metal ion (particularly, a free acid group or a group capable of forming an acid group by hydrolysis). The polymer (A) is a vinyl-series polymer, a polyester (saturated or unsaturated polyester), or a crosslinked or graft polymerized unsaturated polyester. A sheet and a decorative pack may be formed with the concrete retarder.

  • Patent number: 6713564
    Abstract: A novel star block copolymer which can be made to have a high molecular weight and gives a solution having a lower viscosity than solutions of linear polymers having the same molecular weight as the copolymer and which is expected to be used as a resist material; and a process for producing the copolymer. The star block copolymer having alkenylphenol skeletons is obtained by homopolymerizing by living anion polymerization an alkenylphenol compound in which the hydroxyl group of the phenol moiety has been protected by a saturated aliphatic protective group or copolymerizing the alkenylphenol compound with a vinylaromatic compound by living anion polymerization, subsequently copolymerizing the resultant polymer using a polyfunctional coupling agent such as divinylbenzene to obtain a star block copolymer, and eliminating the saturated aliphatic protective groups with an acid reagent.

  • Patent number: 6653381
    Abstract: Novel compounds derived from traditional semi- drying and non-drying oils featuring internally plasticizing and crosslinkable properties are disclosed and claimed. Preferred embodiments include acrylate or methacrylate esters of hydroxy long-chain olefinic compounds derived from castor oil or lesquerella oil. A process for the preparation of the novel compounds is also disclosed, which involves esterification reaction of ethylenically unsaturated carboxylic acids or its derivatives with substituted hydroxy long-chain olefinic compounds. These compounds are suitable for forming latices, which form films at low minimum film forming temperatures (MFT) ranging from −5 to 10 ° C. and cure to above ambient glass transition (Tg polymers without the use of traditional organic cosolvents which contribute to environmental pollution via volatile organic compounds (VOCs) emissions. These latices are therefore useful in waterborne coatings, contact and pressure sensitive adhesives, and inks.
