Patent number: 5254668Abstract: Amidamines of the following formula are described: ##STR1## where R is independently hydrogen or lower alkyl of 1 to 4 carbon atoms;R' is an alkyl group if k is 1, or an alkylene group if k is greater than 1; where R' has 2 to 18 carbon atoms;R" is independently lower alkylene of 2 to 4 carbon atoms;R'" is independently straight or branched lower alkylene of 2 to 6 carbon atoms;x is independently 1 to 200;y is independently 1 to 300;z is independently 1 to 200;p is independently 2 to 11; andk is from 1 to 8; where the x and z groups may be distributed in blocks or randomly.These compositions are made by reacting a cyclic lactam with an etheramine. Incorporation of increasing quantities of the polyetherpolyamine did not decrease the crystalline melting point (T.sub.m) of the resulting copolymer. The polyamidopolyfunctional amines (poly(amide-ether-amide) triblock copolymers) have a relatively low modulus and retain higher use temperatures than current polyetheramide segment block copolymers.Type: GrantFiled: June 29, 1992Date of Patent: October 19, 1993Assignee: Texaco Chemical CompanyInventors: Richard J.

Patent number: 4540768Abstract: Reaction injection molded elastomers made from polymer polyols derived by reacting a liquid terephthalic polyester polyol with an organic polyisocyanate in the presence of a polyether polyol solvent are described. The liquid terephthalic polyester polyol may be made by reacting residue or scrap polyethylene terephthalate (PET) with an oxyalkylene glycol. The oxyalkylene glycol is preferably either diethylene glycol alone or a mixture of diethylene glycol and at least one other oxyalkylene glycol. The liquid terephthalic polyester polyol is preferably distilled to remove ethylene glycol. RIM elastomers made from these polymer polyols have improved hot tear (green strength) and final tear properties than prior art elastomers.Type: GrantFiled: October 9, 1984Date of Patent: September 10, 1985Assignee: Texaco Inc.Inventors: George P.
