The present invention provides a compounding agent which, when used in a rubber composition containing a reinforcing filler, exhibits excellent dispersibility, workability, toughness, low heat build-up, and wear resistance; and a rubber composition containing the compounding agent. A modified butadiene polymer of the present invention has a functional group containing a nitrogen atom and silicon atom at a terminal, a weight average molecular weight of the modified butadiene polymer being from 1000 to 15000, and a molecular weight distribution of the modified butadiene polymer being 2.0 or less.

A cellulose resin composition comprising a cellulose derivative and a lubricant, wherein the cellulose derivative is an acylated cellulose obtained by substituting at least a part of hydrogen atoms of hydroxy groups of a cellulose with an acyl group having 2 to 4 carbon atoms, and the content of the lubricant is in the range of 0.1 to 10% by mass. A cellulose resin composition capable of forming a molded body having a high-quality appearance and scratch resistance is provided.

Polyurethane foams that are hydrophilic but nonetheless have low compression sets are made from a combination of MDI and TDI prepolymers, water, and a polymer polyol. The foams optionally are made incorporating a phase change material in the foam formulation. The phase change material does not require encapsulation.

A reactive mixture and method for making a thermoplastic polyurethane (TPU) flexible foam having a predominantly open-cell structure (open-cell content of ≥50% by volume calculated on the total volume of the foam and measured according to ASTM D6226-10) and an apparent density below 200 kg/m.sup.3.

The present invention discloses a photo-crosslinked rubber composition and application thereof. The rubber composition comprises a rubber matrix and an initiator. Based on 100 parts by weight of the rubber matrix, the rubber matrix comprises a branched polyethylene with a content represented as A, in which 0<A≤100, and an ethylene-propylene rubber with a content represented as B, in which 0≤B<100; and the initiator accounts for 0.1-10 parts, and the initiator includes at least one of a cationic photoinitiator and a free radical photoinitiator. In the rubber composition, the ethylene-propylene rubber is partially or completely replaced by the branched polyethylene. The rubber composition can be used for rubber product crosslinked by ultraviolet light, including wire, cable, film, glove, condom, and medical catheter, which achieves excellent elasticity, electrical insulation property, aging resistance and ozone resistance, and also has good mechanical strength.
