摘要： A method for producing a chloroprene polymer composition containing a chloroprene polymer, the method including: a polymerization step of polymerizing a monomer containing chloroprene at a polymerization rate of 20% or more to obtain a polymer composition containing a chloroprene polymer; and a mixing step of mixing the polymer composition with a rosin containing at least one conjugate resin acid component selected from the group consisting of abietic acid, neoabietic acid, palustric acid, levopimaric acid, and salts thereof, in which a mixed amount of the rosin in the mixing step is more than 0 parts by mass and 23 parts by mass or less with respect to 100 parts by mass of solid content of the polymer composition.

摘要： The disclosure relates to epoxy-based compositions comprising a decarboxylated rosin acid (DCR) component, suitable as an efficient plasticizer. It further improves hardness, elasticity, UV exposure viability properties of the paint and coating compositions. The DCR increases the bio-based renewable material content of a coating formulation and provide solutions for phthalate-free products. The DCR has a density of 0.9 to 1.0 g/cm 3 , a flash point of 135 to 175°C, an acid value of

摘要： A composition for applying onto a road surface and methods for making thereof is disclosed. The composition comprises a binder material of at least a styrenic block copolymer and a resin, which can be pelletized. The SBC is selected from a styrene-isoprene-styrene rubber (SIS) and styrene-isoprene/butadiene-styrene (SIBS); or styrene-ethylene/propylene/styrene-styrene (SEPSS), styrene-ethylene/butylene/styrene-styrene (SEBSS) and mixtures thereof. The binder can be used in road marking compositions or surface treatment compositions when combined with other components such as pigments, glass beads, anti-skid media, fillers, waxes, elastomer/plastomer, and plasticizers.
