A resin composition that allows production of laminated sheets excellent in heat resistance and processability is disclosed. The resin composition comprises: a) a block copolymer, where the block copolymer comprises at least one polymer block comprising polymerized acyclic conjugated diene units, such as butadiene units, and at least one polymer block containing units like a conjugated cyclic diene such as 1,3-cyclohexadiene or monomer units characterized by unit Tg above 100&#xb0; C., b) a curing initiator, and c) optionally diene-based polymer selected from a polybutadiene polymer and the copolymer of butadiene with styrene or other styrenic monomers, c) optional additives comprising but not limited to a multi-functional co-curable additive, a diene based rubber, a halogenated or non halogenated flame retardant, an inorganic or organic filler or fiber, an antioxidant, a adhesion promotor, a film forming.

Block copolymer compositions, prepregs, and laminates made therefrom

A process for pelletizing elastomeric anionically polymerized polymers which comprises subjecting the polymer to solid state extrusion in a single screw extruder with a length to diameter ratio of 10:1 or less wherein the barrel of the extruder has longitudinal grooves and transversally extending pins to increase mixing wherein the temperature in the extruder is sufficient to agglomerate or melt the polymer but be lower than the degradation temperature of the polymer and the speed of the extruder screw is from 30 to 100 rpm.

Conversion of sticky elastomeric polymer crumb into pellets without polymer degradation

A process for finishing a hydrogenated diene polymer by producing porous pellets from a water slurry of the hydrogenated block copolymer. The process comprises adjusting the water content of the slurry to from 9 to 16 percent by weight, moving the slurry through a mechanical two-stage extruder dryer, drying the slurry at a temperature of 100 to 180&deg; C., and recovering porous copolymer pellets having a moisture content of 0.2 to 3.0 percent by weight.

Production of porous diene polymer pellets by mechanical drying

This invention is a process for producing stable polymer emulsions and latexes with an average particle size of less than one micron. The polymers are hydrogenated block copolymers of conjugated dienes and vinyl aromatic hydrocarbons which may or may not contain polar functionality. The process comprises making a polymer cement of the polymer and a blend of a non-aromatic solvent for the vinyl aromatic hydrocarbon block which is immiscible with water and a non-aromatic cosolvent, emulsifying the polymer cement by adding it to an aqueous phase containing at least one surfactant and removing the solvent, cosolvent and excess water.

Process for making submicron stable latexes of hydrogenated block

A method is provided to produce a blown film of a vinyl aromatic/conjugated block copolymer, the method including the steps of:
