ELASTOMERIC COPOLYMERS WITH A HIGH SULFUR CONTENT AND PROCESS FOR THEIR PREPARATION
Elastomeric copolymer with a high sulfur content, comprising sulfur in a quantity higher than or equal to 40% by weight, preferably ranging from 55% by weight to 90% by weight, with respect to the total weight of said elastomeric copolymer, and at least one monomer having general formula (I): CH.sub.2═CH—(CH.sub.2).sub.y-(X).sub.n-(X).sub.m-(CH.sub.2).sub.x—CH═CH.sub.2 (I) wherein: X represents a sulfur atom, a selenium atom, a tellurium atom, preferably a sulfur atom, a selenium atom; y and x, equal to or different from one another, are a whole number ranging from 0 to 4; n and m, equal to or different from one another, are a whole number ranging from 0 to 3, at least one of n and m being equal to 1; said monomer being present in a quantity lower than or equal to 60% by weight, preferably ranging from 10% by weight to 45% by weight, with respect to the total weight of said elastomeric copolymer; provided that, in the case wherein in said general formula (I) X is sulfur, y and x are 1, at least one of n and m must be different from 1 and the sum of n+m must be different from 1. Said elastomeric copolymer with a high sulfur content can be advantageously used in a great many applications such as, for example, thermal insulation, conveyor
Paving Block with Improved Illumination
A paving block with improved illumination (luminescent paving block) preferably includes a concrete base layer and a photoluminescent layer. The photoluminescent layer is formed on top of the concrete base layer. The concrete base layer is preferably created by combining sand, aggregate, water, pigment and cement to form an uncured concrete mixture. The photoluminescent layer preferably includes very fine aggreagate, cement, water, pigment, sand and a polyester resin infused with a photoluminescent pigment or a silica-based glass material infused with photoluminescent pigment. Further, a light transmitting sealant may be placed over the photoluminescent material.
METHOD FOR FORMING CHITIN FILM
A method for forming a chitin film is provided. The method includes the following steps. In a step (a), a chitin suspension is prepared by adding chitin to water. In a step (b), physical forces are provided to process the chitin suspension, so that a mean particle diameter of the chitin is reduced. In a step (c), the chitin suspension is applied to a target, and the chitin film is formed after the chitin suspension is dried.
FUNCTIONAL FABRIC AND METHOD FOR MANUFACTURING THE SAME
A functional fabric and a method for manufacturing the same are provided. The functional fabric includes a polyurethane resin matrix and a plastic optical molding material. In the functional fabric, a content of the polyurethane resin matrix is between 48 wt % and 95 wt %, and a content of the plastic optical molding material is between 5 wt % and 50 wt %. The functional fabric further includes an ultraviolet absorber, an antioxidant additive, and an antibacterial additive. The functional fabric satisfies following test standards: (1) reaching level 4 of a phenolic yellowing test; (2) passing at least 60 hours of a QUV (ASTM G154) test; (3) passing at least four weeks of a water decomposition resistance test under the test conditions of 70° C. and 95% relative humidity; and (4) passing at least one certification of Global Recycle Standard (GRS) and Recycled Claim Standard (RCS).

Process for producing plastic lens and apparatus for producing plastic lens
A process for producing a plastic lens includes a step of stirring and mixing a solution including a polymerization reactive compound in a preparation tank; a step of transferring the polymerizable composition obtained in the step from the preparation tank to a lens casting mold; a step of curing the polymerizable composition; and a step of obtaining a plastic lens molded product by separating the obtained resin from the lens casting mold. The step of transferring the polymerizable composition includes a step of re-mixing the polymerizable composition discharged from the preparation tank and injecting the polymerizable composition into the lens casting mold.
RECYCLED PLASTIC PRODUCTS AND METHODS
A method of making a recycled plastic product includes collecting recyclable plastic materials. The recyclable plastic materials are separated into a plurality of single grade batches of recyclable plastic materials. Each single grade batch is ground into a single grade group of recyclable plastic chips. A single grade portion is weighed out from each single grade group of chips. Each single grade portion is equal in weight within a range of plus or minus 15 percent. Each single grade portion is mixed together to form a multiple grade mixture of recyclable plastic chips. The multiple grade mixture is heated to form a multiple grade blend of molten recyclable plastic. The multiple grade blend is cooled into a form of a solid recycled plastic product. The recycled plastic product comprises multiple grades of recyclable plastic and a volume large enough to encompass a 1.0-inch diameter sphere.
