    摘要: The process of making the soil-repellent and abrasion-resistant monofilament includes transesterifying dimethylterephthalate with ethylene glycol; adding to the resulting reaction mixture from 0.15 to 5 percent by weight of a polydialkylsiloxane of formula I: --CO--R.sub.1 --�Si(R.sub.2).sub.2 --O!.sub.n --Si(R.sub.2).sub.2 --R.sub.1 --CO-- (I), wherein n is the number of repeated --Si(R.sub.2).sub.2 --O-- groups and R.sub.1 or R.sub.2 represent the same or different radicals with 2 to 20 carbon atoms; then polycondensing to form a linear silicone-modified polyethylene terephthalate in which the polydialkyl siloxane of formula I is inserted into a polyethylene terephthalate polymer chain thereof; and extruding the linear silicone-modified polyethylene terephthalate to form a monofilament consisting of the silicone-modified polyethylene terephthalate having a silicon content of 0.05 to 2.0% by weight. The monofilament product has a cross-section with a diameter of from 0.1 to 1.0 mm, a homogeneous composition over the entire cross-section, a tenacity of at least 36 cN/tex, an elongation of less than 44% based on an unstretched portion and a soiling index of less than 10 after five soiling cycles.

    摘要: Polymers are prepared by reaction between a polymer prepared by reaction between (A) an OH terminated reaction product of a polyacid chloride and an organic polymer having substituent groups condensable therewith and (B) a silane or siloxane having a group capable of reaction with substituent groups of the reaction product (A). Reaction product (A) is preferably derived from a polyoxyalkylene glycol and a diacid chloride. Silane or siloxane (B) is preferably an epoxy silane and preferably has at least one silicon- bonded hydrolysable group. Preferred polymers are employed in moisture curable composition, e.g. as sealants.

    摘要: Solvent soluble block copolyesters consisting essentially of units having the formula: ##EQU1## WHEREIN R is an alkylene radical containing at least 3 carbon atoms; R.sup.1 is an alkyl radical and R.sup.2 is an alkyl, alkaryl, aralkyl or aryl radical; A is an alkylene or arylene radical; a is an integer of at least 10; b is an integer of at least 1; c is an integer of at least 2; and d is an integer of at least 2; are formed by first reacting a dihalo-polydiorganosiloxane with a dihydric phenol or other diol and subsequently reacting the resulting reaction product with a dicarboxylic acid halide. These polymers are useful as release agents and leveling agents and find particular utility as abhesive materials for waterless lithographic printing plates.
