摘要 |
{PG,1 A powder composition having good melt flow under zero shear conditions is disclosed. A process for preparing this powder composition is also disclosed. The composition comprises a thermoplastic elastomer such as a block copolymer of styrene and hydrogenated butadiene as well as a melt flow modifier. The melt flow modifier is preferably a partially hydrogenated styrene/alpha methylstyrene random copolymer. The composition may additionally contain adhesion promoters and stabilizers against oxidation and ultraviolet light. A process for coating substrates such as a glass bottle with this composition, as well as the coated glass bottle, is also disclosed.
