The present invention relates to polyester yarn which is characterized in that it is a multifilament yarn substantially comprising polytrimethylene terephthalate, and as well as the strength from the stress-strain curve being at least 3 cN/dtex and the Young's modulus being no more than 25 cN/dtex, the minimum value of the differential Young's modulus at 3-10% extension is no more than 10 cN/dtex and the elastic recovery following 10% elongation is at least 90%. Furthermore, said polyester yarn can be obtained by a method of producing polyester yarn which is characterized in that multifilament yarn obtained by the melt spinning of polymer substantially comprising polytrimethylene terephthalate of intrinsic viscosity Ä eta Ü at least 0.7 is hauled-off at a spinning rate of at least 2000 m/min and, without winding up, subjected to drawing and heat-treatment, after which it is continuously subjected to a relaxation heat treatment at a relaxation factor of 6 to 20% and wound up as a package. Moreover, the present invention also relates to a woven material of outstanding soft-stretchability which is characterized in that the aforesaid polyester yarn is used as the warp yarn and/or the weft yarn in the form of twisted yarn of twist coefficient 10,000 to 20,000. In this way, it is possible to produce yarn stably at a high yarn production rate without package tightening occurring, and, as well as there being little variation in properties in the fibre lengthwise direction, when made into fabric, said fabric stretches at low modulus so there is little sense of tightness, and it is possible to provide polyester yarn and woven materials with a soft handle.

It is intended to provide a composition which has well-balanced pressure-sensitive adhesiveness and cohesive force as well as favorable application properties to the skin, and a patch which has the above-described characteristics and hardly peels off. This object can be achieved by providing a composition comprising an acrylic copolymer containing from 3 to 25% by weight of hydroxyethyl (meth)acrylate as a constituent, a plasticizer and a pseudo-crosslinking compound, wherein the ratio of the content of the plasticizer to the content of the pseudo-crosslinking compound ranges from 30:1 to 250:1, and a patch.

The invention relates to a method for preparing a polymer conjugate, in which a water-soluble polymer employed, the polymer having a linear or branched water-soluble polymer backbone and, at one end of the backbone, a branched moiety linked with two free reactive groups capable of covalent bonding to another molecule. Most specificly, it relates to an activated, substantially water soluble poly(ethylene glycol) having a linear or branched poly(ethylene glycol) backbone and at least one terminus linked to the backbone through a hydrolytically stable linkage, wherein the terminus is branched and has proximal reactive groups is reacted with active moieties in a biologically active agent such as a protein or peptide thus forming conjugates between the activated poly(ethylene glycol) and the biologically active agent.

The present invention relates to the use, for adhesion on hair or fiber-populated surfaces, of hydrogel adhesive characterized by a G'25, (1 rad/sec) or below 1000 Pa, resulting in embedding of the hair of fiber and good adhesion properties on the surface. The invention also encompasses Personal Care Products and Surface Care Articles containing the hydrogel compositions herein.

The present invention includes a co-polymer film which can be applied over a surface of an article to form a continuous surface that is more biocompatible and has a smoother surface morphology than an untreated article. In general the co-polymer film of the invention can be formed by providing a hydrophobic polymer block, such as polydimethylsiloxane (PDMS) with functional -OH end groups and reacting the -OH ends with a conventional monomer or prepolymer of a film-forming polymer capable of reacting with -OH groups. Such reactions are exemplified, using as reactive PDMS a triblock copolymer of the polylactone-polysiloxane-polylactone (PL-PDMS-PL) type, or silicone polyesters. The -OH groups of the polylactone blocks can react with any of a variety of isocyanates in a suitable solvent to form a polymer having PDMS incorporated with its structure. The film can be applied to the surface of an article by any convenient means of coating the article with the reaction mixture in solvent, and allowing the solvent to evaporate.
