New functionalized polybut-1-ene, obtained by mixing olefinic polymer with grafted carboxyl monomer and functional monomer, adding unmodified polybutene-1 and reacting, useful e.g. as coupler in polybut-1-ene/glass fiber composites

摘要

Functionalized polybut-1-ene, obtained by mixing 100 parts by weight of solid phase functionalized olefinic polymers with a portion of grafted carboxyl monomer, 0.1-60 parts by weight of at least a functional monomer or at least a functional monomer containing monomer mixture, and 0.01-20 parts by weight of a free-radical forming initiator; continuously adding 100-4000 parts by weight of unmodified polybut-1-ene and reacting at 150-250[deg] C; and continuously discharging functionalized polybut-1-ene with a functionalized degree of 0.1-5 wt.%, is new. Functionalized polybut-1-ene, obtained by mixing 100 parts by weight of solid phase functionalized olefinic polymers with a portion of grafted carboxyl monomer having a carboxylation degree of 0.2-10 wt.%, 0.1-60 parts by weight of at least a functional monomer or at least a functional monomer containing monomer mixture, and 0.01-20 parts by weight of a free-radical forming initiator with an one-hour half life temperature of 80-240[deg] C; further continuously adding 100-4000 parts by weight of unmodified polybut-1-ene with a molecular weight of 100000-3000000 mole/g via dosing devices into an extruder inlet region of the reaction extruder and reacting at 150-250[deg] C; and continuously discharging functionalized polybut-1-ene with a functionalized degree of 0.1-5 wt.% from the reactor end, is new.
