    摘要： Polyamides containing as much as 50 mole percent nylon-3 units in at least a partially alternating system and exhibiting high glass transition temperatures (Tg) can be prepared from N,N'-terephthaloyldi-beta-alanine and a diamine, such as bis(p-aminocyclohexyl)methane. Properties of such polyamides can be controlled by choice of the diamine and the preparation temperature without loss of the high Tg. The polyamides of this invention exhibit utility in comfort fiber applications.

    摘要： There are disclosed and claimed novel polyamides on the basis of a) 1,3-bis-(amino-methyl)-cyclohexane or mixtures thereof with 1,4-bis-(amino-methyl)-cyclohexane; b) one or several aromatic dicarboxylic acid (s); and c) one or several aliphatic amino-carboxylic acid(s); and the process of making the same. These polyamides combine high transparency with very good thermal and mechanical properties, namely high second order transition temperatures, good form stability at higher temperatures, high hardness and impact strength.

    摘要： There is disclosed a process for the preparation of novel transparent polyamides with improved properties. These polyamides are obtained by polycondensing 1,3-bis-(amino-methyl)-cyclohexane, which can be partly substituted by the 1,4-derivative, at least one aromatic dicarboxylic acid and at least one amino-carboxylic acid or the lactam thereof with at least one aliphatic straight chain or branched diamine or/and at least one aliphatic straight chain or branched dicarboxylic acid.

    摘要： 1. A PROCESS FOR PRODUCING SHAPED ARTICLES OF POLYAMIDES HAVING AN ELEVATED SOFTENING POINT AND IMPROVED HEAT RESISTANCE COMPRISING MELT SHAPING AT A TEMPERATURE ABOVE THE INITIAL SOFTENING POINT OF SAID POLYAMIDE WHICH IS SELECTED FROM THE GROUP CONSISTING OF (A) A HOMOPOLYAMIDE COMPOSED OF RECURRING UNITS OF A 1,4-DIHYDROTEREPHTHALIC ACID AMIDE OF THE FORMULA

    -(CO-(1,4-PHENYLENE)-CO-NH-X-NH)-

    WHEREIN X IS A DIVALENT ORGANIC RESIDUE OF A DIAMINE AND THE ACID HALIDES AND ESTERS THEREOF; AND (B) COPOLYAMIDE CONTAINING AT LEAST 5 MOL PERCENT, BASED ON THE TOTAL CARBOXYLIC ACID COMPONENT OF THE POLYAMIDE OF 1,4-DIHYDROTEREPHTHALIC ACID UNITS OF THE FORMULA

    -(CO-(1,4-PHENYLENE)-CO)-

    SAID COPOLYAMIDE PREPARED BY POLYMERIZING SAID 1,4-DIHYDROTEREPHTHALIC ACID UNITS OR THE ACID HALIDE OR ESTER DERIVATIVES THEREOF WITH A DIAMINE AND A MEMBER SELECTED FROM THE GROUP CONSISTING OF DICARBOXYLIC ACIDS, OMEGAAMINOCARBOXYLIC ACID AND LACTAMS; AND HEATING SAID POLYAMIDE AT A TEMPERATURE OF AT LEAST 100*C. BUT BELOW THE HEAT DECOMPOSITION TEMPERATURE OF SAID POLYAMIDE DURING A PERIOD OF AT LEAST ABOUT 30 SECONDS TO THEREBY ELEVATE THE SOFTENING TEMPERATURE OF SAID POLYAMIDE BY AT LEAST 10*C. WITH THE PROVISO THAT SAID POLYAMIDE IS PREPARED UNDER SUCH CONDITIONS THAT ITS SOFTENING POINT BEFORE SAID HEAT TREATMENT WILL BE SUBSTANTIALLY BELOW ITS HEAT DECOMPOSITION TEMPERATURE.

    摘要： A POLY(HEXAMETHYLENE ADIPAMIDE) (NYLON 6.6) FIBERFORMING COMPOSITION IS DESCRIBED AS WELL AS THE SHAPED ARTICLES MADE THEREFROM PARTICULARLY FIBERS, WHICH ARTICLES HAVE IMPROVED PHYSICAL AND CHEMICAL PROPERTIES. THE NYLON 6.6 COMPOSITION IS A COPOLYMER OF PRIMARILY HEXAMETHYLENE ADIPAMIDE AND A SMALL BUT EFFECTIVE AMOUNT OF AN W-AMINOCARBOXYLIC ACID OR A DERIVATIVE THEREOF. THE AMOUNT OF W-AMINOCARBOXYLIC ACID, OF WHICH E-CAPROLACTAM IS MOST PREFERRED, COPOLYMERIZED WITH THE HEXAMETHYLENE DIAMMONIUM ADIPATE IS LESS THAN THAT WHICH SUBSTANTIALLY AFFECTS NORMAL NYLON 6.6 CHARACERISTICS YET IS SUFFICIENT TO IMPROVE PROCESSIBILITY THROUGH SPINNING, DRAWING AND BEAMING, DYE UNIFORMITY, AND MECHANICAL QUALITY. THE CONTINUOUS POLYMERIZATION OF THE PRESENT COMPOSITION IS ALSO DESCRIBED AS WELL AS THE METHOD OF SPINNING SAID COMPOSITIONS.

    摘要： HIGH SHRINKAGE POLYMERS USEFUL IN PRODUCTION OF HOSIERY AND CRIMPY CONJUGATE YARNS ARE PROVIDED BY LINEAR RANDOM COPOLYAMIDES OF (A) AT LEAST ONE ALIPHATIC DIAMINE HAVING THE FORMULA NH2(CH2)NNH2 IN WHICH N IS AN INTEGER FROM 2 TO 10, (B) AT LEAST ONE ALIPHATIC DICARBOXYLIC ACID HAVING THE FORMULA HOOC(CH2)MCOOH IN WHICH M IS AN INTEGER FROM 4 TO 20 AND (C) 5-T-BUTYLISOPHTHALIC ACID. EVEN GREATER SHRINKAGE RESULTS WHEN A PORTION OF THE ALIPHATIC DIAMINE COMPONENT (A) IS REPLACED WITH 1,4CYCLOHEXANEBIS(METHYLAMINE). FIBERS MADE FROM THE NOVEL COPOLYAMIDES ARE ALSO USEFUL FOR TIRE REINFORCEMENT DUE TO THEIR LOW FLATSPOTTING TENDENCY OVER WIDE RANGES OF TEMPERATURE AND HUMIDITY.
