Coextruding tacky amorphous propylene copolymer composition

摘要: Disclosed is a process for producing non-blocking slats of normally tacky amorphous propylene copolymers. The entails coextruding the copolymer with low viscosity polyolefin such as polyethylene wax forming core covered sheath wax. coextruded article cooled, cut (while exposing less than 40 percent core) and then coated non-tacky powder; thereby, slats. also novel composition containing no more 90 weight up to 70 an alpha olefin comonomer having needle penetration greater 100 dmm at 23° C. Brookfield Thermosel Viscosity below 1000 cP 190°
