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.

Roadway surface compositions and pelletized binder materials thereof

A styrenic block copolymer is disclosed, having a formula, A-B-A, A-B-B-A, (A-B-A)X, (A-B)X or mixtures thereof, wherein n is from 2 to 30, and X is residue of a coupling agent. Each A block is independently a polystyrene having 10-63 wt. % 1,1-diphenylethylene, a GPC peak molecular weight from about 5-40 kg/mol, and forms 10-40 wt. % of the copolymer. Each B block is independently a poly(1,3-diene-co-styrene) comprising: (i) &#x3e;90 wt. % of polymerized isoprene units relative to the weight of the polymerized 1,3-diene, where S is &#x3c;40, and (S+V) is 18-75; (ii) &#x3e;90 wt. % of polymerized butadiene units relative to the weight of the polymerized 1,3-diene, where S is &#x3c;40, and (1.2*S+V) is 60-120; or combinations thereof 'S' represents the polystyrene content, and 'V' represents the 1,3-diene content having pendant 1,2- and/or 3,4-vinyl groups in the B block.

Block copolymers and uses thereof

A styrenic block copolymer having one or more polymer blocks A and one or more polymer blocks B is disclosed, where 'A' is a poly(vinylaromatic) block having a molecular weight of greater than 5 kg/mol. The 'B' block has a molecular weight of more than 15 kg/mol, and comprises polymerized 1,3-diene units and vinylaromatic units, wherein the polymerized vinylaromatic units represent 5-40 wt. % of the overall weight of the block &#x201c;B&#x201d;. The polymerized 1,3-diene units comprise more than 80 wt. % of polymerized isoprene units in which 45-80 mol % are 1,4-isoprene addition units. The blocks &#x201c;A&#x201d; and &#x201c;B&#x201d; represent from &#x3e;5 to &#x3c;40 wt. %, and &#x3e;33 to &#x3c;95 wt. %, respectively, relative to the overall weight of the block copolymer. The polymers have physical properties that make them valuable, e.g., as vibration damping materials.

A styrenic triblock copolymer composition with a combination of excellent tensile strength and high melt index, excellent for manufacturing, finishing and handling, forming stable pellets, for use in applications including but not limited to adhesive, coating, and flexographic printing. The composition comprises a first block which is a polymer of a monoalkenyl arene; a second block which is polymer of a conjugated diene and a third block which is a polymer of a monoalkenyl arene wherein a peak molecular weight of the third block is from about 0.06 to about 0.4 times that of the first block.

Highly asymmetric triblock polymer compositions and methods of making same

A block copolymer comprising: at least one monoalkenyl arene monomer polymer block (A) and copolymer block (B) containing myrcene, said copolymer block B also including:

Block copolymers containing a copolymer myrcene block

The invention relates to a novel block copolymer comprising at least one polymeric monoalkenyl arene block and at least one polymeric myrcene block having a low and stable viscosity and having good adhesive properties when used in an adhesive composition or as a damping material. An adhesive composition is also described, preferably containing an SMS triblock optionally mixed with an SM diblock. The adhesive composition comprises: 1) a block copolymer having at least one polymeric monoalkenyl arene block and at least one polymeric myrcene block; 2) a tackifier; 3) optional plasticizer; and 4) optionally a stabilizer. Compared with adhesive compositions comprising SIS block copolymers, those comprising SMS block copolymers have lower and more stable viscosity.

Adhesive compositions containing a block copolymer with polymyrcene

A curable polymeric composition is herein disclosed. According to one embodiment, a curable polymeric composition comprises a thermoplastic block copolymer containing at least two polymer blocks A separated by at least one polymer block B. Each polymer block A is primarily a poly(monovinyl aromatic hydrocarbon) block, and polymer block B includes hydrogenated conjugated didne. The solid curable polymeric composition further comprises a curable functional compound compatible with polymer block A. The solid curable polymeric composition optionally comprises an initiator, a plasticizer, an antioxidant; a tackifyer and an aromatic resin.
