摘要:
Polyetherimide compositions having low warp and conductive properties are provided. The compositions are prepared by combining a polyetherimide resin or polyetherimide-copolymer resin and a filler wherein the filler comprises a plate-like filler and a conductive filler.
摘要:
A thermoplastic resin composition contains an aromatic carbonate resin, a rubber modified graft copolymer comprising a discontinuous rubber phase dispersed in a continuous rigid thermoplastic phase, wherein at least a portion of the rigid thermoplastic phase is chemically grafted to the rubber phase, and a flame retarding amount of an alkali metal or alkaline earth metal salt of an alkylbenzenesulfonic acid flame retardant.
摘要:
A thermoplastic resin composition comprises a compatible resin blend of a polyester sulfonate salt ionomer and a polyamide and at least one difunctional epoxy compound having at least one cyclohexane ring moiety and two terminal epoxy functional groups, wherein at least one of the two terminal epoxy functional groups is a substituent on the at least one cyclohexane ring moiety; and, optionally, a catalyst compound or rubber impact modifier.
摘要:
A thermoplastic resin composition is provided comprising a polycarbonate resin, polyester resin, and glass fibers which have been treated with polyolefin wax and optionally a functionalized silane. The nature of the coating on the glass fibers provides the composition with improved impact strength over bonding glass. The composition is useful as a molding material.
摘要:
A novel polyester composition is disclosed comprising a linear polyester resin, a difunctional epoxy compound and a catalyst. The novel polyester compositions have excellent melt viscosity properties including excellent retention of melt viscosity after aging.
摘要:
Compounds of Formula I ##STR1## wherein Z is an aromatic group, each R is individually selected from the group consisting of alkyl groups of from 1 to about 12 carbon atoms, thioalkyl groups of from 1 to about 12 carbon atoms, and halogen atoms, n is from 1 to about 6, and x is from 0 to 7, are suitable for use in preparing rubber latex particles. The rubbers are useful as substrates in graft copolymers and the resulting graft copolymers are suitable for use in thermoplastic blend compositions, particularly with transparent polymers. The rubber materials are advantageous in that they exhibit low glass transition temperatures and high refractive indices.
摘要:
A method of coating is disclosed which is based on applying a composition which is based on colloidal silica dispersed in a silanol or methacrylic derived polymer system or an aminoplast resin to an article of a polybutylene terepthalate or polyethylene terephthalate, or blends of polybutylene terephthalate and polyethylene terephthalate, which optionally include a polycarbonate, or optionally include a polyether ester or polyetherimide ester and a heavy inorganic filler.
摘要:
Novel polyphenylene ether-polyamide compositions having improved compatibility, elongation and impact properties as well as improved processability are prepared comprising one or more polyphenylene ethers, one or more polyamides and a property improving silane derivative compound having in the molecule both (a) at least one silicon bonded to a carbon through an oxygen link and (b) at least one ethylenic carbon-carbon double bond or carbon-carbon triple bond and/or functional group selected from the group consisting of an amine group or a mercapto group, with the proviso that the functional group is not directly bonded to a silicon atom. These compositions may further comprise a polymeric impact modifier therefore and/or an inorganic reinforcing additive and/or other polymers including alkenyl aromatic polymers.
