pc/pbt alloy
pc/pbt alloy, pbt has excellent mechanical properties, chemical corrosion resistance&easy molding. the blending of pbt&pc can improve pc fluidity, improve processability&chemical resistance. because pbt is a crystalline polymer, it is easy to phase separation when mixed with pc,&its interfa-l adhesion is not good, so its impact toughness is not ideal. a certain amount of elastomers is usually added to improve the impact strength of the blends. the zinc salts of thermoplastic elastomer ethylene / methacrylate copolymers play a role in compatibilization&toughening of pc/pbt blends. the addition of some nucleating agent can improve the crystallinity of the blends; adding a small amount of low pressure polyethylene in pc/pbt blend system, can improve the flowability of the blend, play a toughening effect on blends,&can improve the appearance of alloy; added in pc/pbt ethylene / vinyl acetate copolymer can further enhance the compatibility&improve impact resistance strength; esterification reaction between pc&pbt, can improve the compatibility, japanese researchers using pc&pbt in the presence of a transesterification catalyst, prepared pc/pbt blends, good comprehensive performance, but also has better transparency;&pc with similar refractive index of glass fiber reinforced pc/pbt, not only the excellent comprehensive performance system.&good transparency, can do instead of glass materials. foreign pc/pbt alloy products are mainly used for automobile bumpers, packaging film materials, car base&seat, etc.
pet pet has good mechanical properties&chemical resistance. pc/pet has both the rigidity&heat resistance of pc,&the solvent resistance of pet. moreover, the addition of pet can improve the processing fluidity of pc. domestic researchers found that when the pc/pet ratio is 1/3, the interface layer forms between the two phases,&the pc/pet compatibility is best at this time. in addition pc&pet ester exchange reaction is one of the best ways in which the catalyst compatibility, selection of a very large impact on the reaction, the catalyst of lanthanide catalyst&the traditional study found (such as titanium) have higher catalytic activity,&there is no side effects, also found that the ester exchange reaction occurs mainly in the interface. in pc/pet blends, the toughness&impact strength of the alloy can be improved by adding elastomer, such as butyl acrylate.
the research&development of pc alloy change rapidly, there are a variety of pc alloy has been developed&marketed, espe-lly pc modified polyester blends, such as pet/pcl (multiblock copolyesters by ethylene glycol, a low molecular weight polycaprolactone&terephthalic acid copolymer made) blended with pc modification; by 1, modified polyester pc blended with 4 - cyclohexane two methanol, ethylene glycol&terephthalic acid, can significantly improve the pc flexural modulus&tensile strength; polycaprolactone with glass fiber as reinforcing material, promote the pcl&pc were mixed with modified transesterification catalyst, transparent material can get good processing performance, high rigidity; poly (1, 4 - two - 1 4 cyclohexane carboxylic acid, cyclohexane two methanol) ester modified pc, pc can significantly improve the transparency&yellowing resistance, can be used as optical materials; liquid crystal polyester modified pc it can be used to improve the melting&mechanical properties of pc.
