A molded article for protecting a transition section of a multi-wire cable. The article includes a transition cover having an elastomeric skin and further including a cable receiving tube, having an open channel therein. The cable receiving tube has intersection with each of a plurality of wire cove
A molded article for protecting a transition section of a multi-wire cable. The article includes a transition cover having an elastomeric skin and further including a cable receiving tube, having an open channel therein. The cable receiving tube has intersection with each of a plurality of wire cover sleeves to provide passage openings from the open channel of the cable receiving tube to each of the plurality of wire cover sleeves for insertion of at least one wire of the multi-wire cable therein. A stress relief pocket formed in the elastomeric skin, adjacent to at least a portion of each intersection, extends towards the open channel and includes at least one crease to accommodate expansion of the stress relief pocket from a partially folded condition to reduce the concentration of stress at an intersection during movement of the transition cover from a relaxed condition to a stretched condition.

The method of claim 1 comprising conducting the reaction of step (a) at a temperature of from about 120 to 280° C. 20. The method of claim 1 wherein the reaction of step (a) is conducted at a temperature of from about 130 to 190° C. 21. The method of claim 19 further comprising conducting the reaction of step (a) in the presence of an esterifcation or transesterification catalyst. 22. The method of claim 1 comprising conducting the reaction of step (b) at a temperature of from about 150 to 280° C. 23. The method of claim 22 wherein the reaction of step (b) is conducted at a temperature of from about 180 to 260° C. 24. The method of claim 22 further comprising conducting the reaction in a vacuum of from about 600 to 0.5 mmHg. 25. The method of claim 1 wherein the co-poly(ethylene terephthalate) is a co-polymer of poly(ethylene terephthalate) with a comonomer selected from the group consisting of isophthalate, diethylene glycol, propylene glycol, and 1,4-cyclohexanedimethanol. 26. The method of claim 1 wherein step (a) further comprises reacting the compounds of Formulas (I) and (II) in the presence of at least one compound of Formula (III) R2--(COOZ)p (III) wherein R2is selected from the group consisting of an alkyl group and an aryl group which may be substituted with an alkyl group or an aryl group, Z is selected from the group consisting of hydrogen and an alkyl group and p is a positive integer. 27. The method of claim 26 wherein R2is an alkyl group having 1-12 carbon atoms. 28. The method of claim 26 wherein Z is an alkyl group having 1-4 carbon atoms. 29. The method of claim 26 wherein R2is phenyl or naphthyl. 30. The method of claim 26 wherein p is 1 or 2. 31. The method of claim 26 wherein the compound of Formula (III) is selected from the group consisting of terephthalic, isophthalic, orthophthalic, 1,2-naphthalene dicarboxylic, 1,4-naphthalenedicarboxylic, 1,5-naphthalenedicarboxylic, 1,6-naphthalenedicarboxylic, 1,7-naphthalenedecarboxylic, 1,8-naphthalenedicarboxylic, 2,3-naphthalenedicarboxylic, 2,6-naphthalenedicarboxylic, 2,7-naphthalenedicarboxylic acids and their corresponding alkyl esters. 32. The method of claim 1 wherein step (a) further comprises reacting the compounds of Formula (I) and (II) in the presence of at least one compound of Formula (IV) wherein R3and R4are each independently selected from the group consisting of hydrogen and an alkyl group and q is a positive integer. 33. The method of claim 32 wherein R3is an alkyl group having 1-4 carbon atoms. 34. The method of claim 32 wherein R4is an alkyl group having 1-12 carbon atoms. 35. The method of claim 34 wherein R4is methyl or lauryl. 36. The method of claim 32 wherein q is 2 to 20. 37. The method of claim 32 wherein the compound of Formula IV is selected from the group consisting of polyethylene glycol, polypropylene glycol, block copolymers of polyethylene glycol and polypropylene glycol and alkyl monoethers thereof. 38. The method of claim 1 comprising intermittently adding the homo- or co-poly(ethylene terephthalate) to the ester compound intermediate. 39. The method of claim 1 comprising continuously adding the homo- or co-poly(ethylene terephthalate) to the ester compound intermediate.
