Abstract: An electrical component (20) comprises electrical circuit means (22) and housing member (50) disposed over a first portion (24) of the electrical circuit means (22). The circuit means (22) has a second portion (30) extending outwardly from the housing member (50) at a junction (32) with the first portion (24). The housing member (50) comprising a dielectric amorphous thermoplastic resin which is molded over the first portion (24) of the electrical circuit means (22). The composition seals the interface (56) of the housing (50) and the extending second portion (30) of the circuit means (22) and maintains sealing engagement therewith when stress is applied to the interface (56).

Abstract: Mixtures of (A) mixed esters of (a) C.sub.2-10 alkanepolyols, (b) certain dicarboxylic acids, and (c) C.sub.12-30 aliphatic hydrocarbon monocarboxylic acids, said esters having hydroxyl and acid numbers of 0 to 6 and having a molecular weight above 524, and (B) esters of C.sub.32-72 aliphatic monools with C.sub.18-72 aliphatic hydrocarbon monocarboxylic acids (the weight ratio of A to B being between 9:1 and 1:3) are useful as lubricants and detackifiers in thermoplastic molding compositions.

Abstract: Poly(tetramethylene terephthalate)-polyether block copolymers having materially increased heat deflection temperatures and incorporating within the polymer chain in random distribution 1 percent to 7 percent by weight of the polyether, poly(tetramethylene ether glycol) or polyethylene oxide; the polyether being added to the reaction mixture in the course of the polymerization reaction.
