Abstract:
ELASTIC MOULDING COMPOSITIONS ON THE BASIS OF POLYACETALS ARE PREPARED BY REACTING COPOLYMERS OF TRIOXANE CONTAINING FREE AMINO GROUPS WITH POLYETHERS CONTAINING ISOCYANATE GROUPS. THE ELASTIC MOULDING COMPOSITIONS SO OBTAINED ARE THERMOPLASTIC AND DISTINGUISHED BY HIGH IMPACT STRENGH AND ARE USED ALONE OR IN ADMIXTURE WITH POLYACETALS TO FROM SHAPED PARTICLES.
Abstract:
THERMONPLASTIC MOULDING COMPOSITIONS WITH HIGH IMPACT STRENGTH ARE PREPARED BY MIXING A POLYACETAL WITH A TWOPHASE MIXTURE WHICH IS COMPOSED OF AN ELASTOMERIC AND A HARD POLYMER, THE ELASTOMERIC PHASE BEING DISPERSED IN THE HARD PHASE. THE MOULDING COMPOSITIONS OBTAINED CAN BE WORKED THERMOPLASTICALLY AND ARE SUITABLE FOR THE MANUFACTURE OF SEM-FINISHED AND FINISHED PRODUCTS, FOR EXAMPLE SHAPED ARTICLES, HOUSEHOLD ARTICLES, AND MACHINE PARTS.
Abstract:
Polyacetals, consisting of homo- or copolymers of formaldehyde or trioxane and having a good flowability as well as a resistance to alkali and solvents, are used as thermoplastic adhesives for textiles, paper and wood.
Abstract:
Copolymers of trioxane with determined cyclic formals are used for making stiff supporting bandages. The thermoplastic-moulding compositions are applied in the plasticized state without a carrier material or together with a fabric to the part of the body to be treated and then allowed to solidify.
Abstract:
THERMOPLASTIC MOULDING COMPOSITIONS COMPRISING A LINEAR SATURATED POLYESTER AND POLYACETALS, FROM WHICH SHAPED ARTICLES CAN BE MADE HAVING A GOOD SURFACE HARDNESS AND A HIGH IMPACT STRENGTH AND BENDING STRENGTH.
Abstract:
There are disclosed and claimed novel mixtures of thermoplastic polyamides, namely mixtures of at least one polyamide derived from 1,3-bis-aminomethyl-cyclohexane, which optionally is partly replaced by 1,4-bis-aminomethyl-cyclohexane and optionally at least one aliphatic diamine, at least one aromatic dicarboxylic acid and optionally at least one aliphatic dicarboxylic acid, and optionally at least one aminocarboxylic acid, with at least one polyamide each of the polyamide 6 and/or polyamide 6,6 types. The mixtures of the invention combine good mechanical with good flow properties.
